Environmental pollution has been a fact of life for many centuries, though it became a real issue after the start of the industrial revolution. An estimated 6.5 million premature deaths have been linked to air pollution every year.
In order to properly combat this growing issue, the world’s leading minds have turned to a more effective tool for environmental analysis; numerical simulation. Computational fluid dynamics has proven to be a powerful tool when it comes to predicting and controlling air, water, and noise pollution.
Join PADT’s CFD Team Lead Engineer Clinton Smith to learn how ANSYS fluid mechanics solutions provide insight and detailed understanding of the formation and dispersion of pollutants such as NOx, SOx, CO & Soot as well as effective ways for modelling pollution control equipment such as ESP’s, bag filters, and wastewater treatment plants.

We are pleased to announce that the US Army has awarded PADT a Phase I SBIR Grant to explore novel geometries for combustor cooling holes. This is our 15th SBIR/STTR win.
We are excited about this win because it is a project that combines Additive Manufacturing, CFD and Thermal Simulation, and Design in one project. And to make it even better, the work is being done in conjunction with our largest customer, Honeywell Aerospace.
We look forward to getting started on this first phase where we will explore options and then applying for a larger Phase II grant to conduct more thorough simulation then build and test the options we uncover in this phase.
Read more below. The official press release is here for HTML and here for PDF.

The Project Involves the Development of Sand-Plugging Resistant Metallic Combustor Liners
TEMPE, Ariz., August 15, 2019 ─ In recognition of its continued excellence and expertise in 3D printing, simulation, and product development, PADT announced today it has been awarded a $107,750 U.S. Army Phase I Small Business Innovation Research (SBIR) grant. With the support of Honeywell Aerospace, PADT’s research will focus on the development of gas turbine engine combustor liners that are resistant to being clogged with sand. The purpose of this research is to reduce downtime and improve the readiness of the U.S. Army’s critical helicopters operating in remote locations where dirt and sand can enter their engines.
“PADT has supported advanced research in a wide variety of fields which have centered around various applications of our services,” said Eric Miller, co-founder and principal, PADT. “We’re especially proud of this award because it requires the use of our three main areas of expertise, 3D printing, simulation and product development. Our team is uniquely capable of combining these three disciplines to develop a novel solution to a problem that impacts the readiness of our armed forces.”
The challenge PADT will be solving is when helicopters are exposed to environments with high concentrations of dust, they can accumulate micro-particles in the engine that clog the metal liner of the engine’s combustor. Combustors are where fuel is burned to produce heat that powers the gas turbine engine. To cool the combustor, thousands of small holes are drilled in the wall, or liner, and cooling air is forced through them. If these holes become blocked, the combustor overheats and can be damaged. Blockage can only be remedied by taking the engine apart to replace the combustor. These repairs cause long-term downtime and significantly reduce readiness of the Army’s fleets.
PADT will design various cooling hole geometries and simulate how susceptible they are to clogging using advanced computational fluid dynamics (CFD) simulation tools. Once the most-promising designs have been identified through simulation, sample coupons will be metal 3D printed and sent to a test facility to verify their effectiveness. Additionally, PADT will experiment with ceramic coating processes on the test coupons to determine the best way to thermally protect the 3D printed geometries.
“When we developed new shapes for holes in the past, we had no way to make them using traditional manufacturing,” said Sina Ghods, principal investigator, PADT. “The application of metal additive manufacturing gives PADT an opportunity to create shapes we could never consider to solve a complex challenge for the U.S. Army. It also gives us a chance to demonstrate the innovation and growth of the 3D printing industry and its applications for harsh, real-world environments.”
Honeywell joined PADT to support this research because it is well aligned with the company’s Gas Turbine Engine products. The outcome of this research has the potential to significantly improve the performance of the company’s engines operating in regions with high dust concentrations.
This will be PADT’s 15th SBIR/Small Business Technology Transfer (STTR) award since the company was founded in 1994. In August 2018, the company, in partnership with Arizona State University, was awarded a $127,000 STTR Phase I Grant from NASA to accelerate biomimicry research, the study of 3D printing objects that resemble strong and light structures found in nature such as honeycombs or bamboo.

Engineering simulation has traditionally been used for new product design and virtual testing, eliminating the need to build multiple prototypes prior to product launch.
Now, with the emergence of the Industrial Internet of Things (IIoT), simulation is expanding into operations. The IIoT enables engineers to communicate with sensors and actuators on an operating product to capture data and monitor operating parameters. The result is a digital twin of the physical product or process that can be used to monitor real-time prescriptive analytics and test predictive maintenance to optimize asset performance.
Join PADT’s Senior Analyst & Lead Software Developer Matt Sutton for an in depth look at how digital twins created using ANSYS simulation tools optimize the operation of devices or systems, save money by reducing unplanned downtime and enable engineers to test solutions virtually before doing physical repairs.
This webinar will include an overview of technical capabilities, packaging for licensing, and updates made with the release of ANSYS 2019 R1.

I was on the gondola up at Keystone for night-skiing a week ago, after a long day at Beaver Creek, because the last thing I am going to do at 3:00 pm is try to make it back to Denver, as everyone knows it’s hardly more than a parking lot at that point. As it gets later, there’s nothing like a solo gondola ride, however, a solo ride would stop this story right about now.
On the gondola, I overheard a conversation where one gentleman was discussing how he was unable to open the hatch of his vehicle when his skis are in his roof rack. That’s fair, I know older WRX wagons with the spoiler would not be able to open with skis on the roof no matter what, so I figured that was the case. It turns out, that was NOT the case. The reason his hatch would not open was that he orients the skis with the tails forward because it is ‘more aerodynamic’ that way… I was skeptical, but held my tongue, knowing that I had the tools at my disposal to investigate!
I decided to make a model that would allow me to simulate various conditions to get to the bottom of this. My initial hypothesis is that the addition of the ski rack and crossbars is what has the largest effect on aerodynamics, and orientation of the skis probably has a negligible effect after that. As a side note, I am solely concerned with aerodynamics in this case, and am not worrying about the amount of the ski’s base material that is exposed for a given orientation. I am of the mindset that tree trunks and hidden rocks on the mountain are more of a danger to your bases than small rocks on the highway anyway. If you are waiting to comment, “Just get a roof box!”, I understand as I own both a box and a rack at this point, and they both have their advantages, and I will not be exploring the aerodynamics of a box…
…yet…
I was able to start by finding some faceted geometry of a Subaru Forester online (I’m from Colorado, can you tell?) and was able to import that into ANSYS Spaceclaim. Once in Spaceclaim, I was able to edit the faceted geometry to get nice exterior panel surfaces, which I then combined to get a single clean faceted exterior for the car.
After that, I used Spaceclaim to generate the remainder of the rack and skis, including crossbars, a ski rack, and a pair of skis (Complete with the most detailed bindings you have ever seen!). I made a combined part of the crossbars, rack, and skis for each one of my orientations, as this allows me to report the forces on each combined part during the simulation.
For the simulation, I used ANSYS Discovery Live, the newest tool from ANSYS that allows for instant and interactive design exploration. This tool lets me actively add my CAD geometry and shows results in realtime. I was able to start with just the car and then add and swap my ski/rack geometry with simple button clicks. With traditional simulation tools, I would have needed to create a mesh for each one of these cases, analyze them one at a time, and the post-process and compare results after the fact. After launching Discover Live, it’s as easy as selecting the type on analysis I want to run.
Once I have selected ‘Wind Tunnel’ for my solution, I can select my geometry, and then am prompted for the direction of flow, as well as selecting the ‘floor’ of my domain. Once that is done, results show up on the screen instantly. I only needed to modify the flow velocity to ~65 mph. I am most interested in the force on the faces of the combined crossbars, rack, and skis in each orientation, so I created Calculations for each one, which is done by simply selecting the part and using the popup toolbar to create the graph.
I was already off and running. I ran each one of the cases until the force plot had become steady.
Seeing that the force results for the Tips Forward vs. Tails Forward cases were very similar, I decided I should also run a ‘Bases Up’ Orientation, even though I STRONGLY advise against this, as UV wrecks the base material of your skis/snowboard.
In addition to the contour plot shown in the images above, you can also use emitters to show streamlines and particle flow, which also give some pretty neat visualizations.
The graph plots show values for the Total Y Force for Tips Foward, Tails Forward, and Bases Up orientations to be 37.7 N, 39.1 N, and 37.1 N, respectively. Using Discovery Live, I was able to quickly run all 3 of these simulations, showing that there is not a major difference in the forces on the ski rack between the three orientations. So, put the skis on the roof in the direction that makes life easiest for you, and keep those bad boys paired to protect your bases from the sun, because splitting them isn’t going to help with aerodynamics anyway!
Next steps would be taking a specific case and running in 2D, then 3D, in ANSYS Fluent.
