I have always been fascinated by turbomachinery: pumps, compressors, turbochargers, state-of-the-art aircraft engines etc. Anything that spins is of interest. This is one of the key reasons why I love going to work at ANSYS every day. I can contribute to creating the best turbomachinery simulation solutions.
Demonstration simulation of the turbine side of a turbocharger, using a geometry design provided by our partner PCA Engineering.
I am often asked “What are you working on? Turbines? Compressors? Hydraulic turbines?” Well, the answer is all of the above, and more. This is because our physics solutions are not limited by machine type, material or flow regime. Similarly, our turbomachinery-specific pre- and post-processing tools apply across machine categories. Besides, complex machines such as an aircraft engine have many parts: compressor, turbine, combustion chamber, complex secondary flow channels, etc. So with each new release of ANSYS, we strive to improve the simulation solutions that we provide to our turbomachinery customers.
I am sure many of you have heard of clean diesel. And, probably asked yourself what is it and how is it different from regular diesel. Are we refining fuel more — why is it called clean? That is just one part of it. Clean diesel is really a three-part system. One part is cleaner fuel, the second part is improvement in the combustion — more advanced engines— and the third part is new technologies that control emission and exhaust gasses. There are different emission control technologies that can further reduce emission from the diesel engines, but most dominant are diesel particulate filters (DPF), exhaust gas recirculation (EGR), selective catalytic reduction (SCR) and diesel oxidation catalysts (DOC).

“Meshing”… Usually throwing this single word to a group of structural or CFD analysts will start interesting and passionate discussions. Meshing is definitely a key part of the simulation process and requires attention. As analysts, how many hours did we or do we spend on meshing? Probably too many — especially if you have been in the simulation world for many years and started when automation of meshing was not so common. But after all, meshing is just one of the tools that we need to get accurate results and we should spend more time looking at simulation results than meshing our models. Continue reading →
Another release of ANSYS fluid dynamics products, another round of great new capabilities. While some may say that a picture is worth a thousand words, I invite you to view the video below for more than 16,000 words on 16 Cool New Features of ANSYS Fluid Dynamics 16.0. And they are all winners — so this is not a ranking, just a list! Continue reading →
What do Tesla Motors, BMW, Honda, Toyota, Ferrari, Denso, Panasonic, SL Corporation, Cummins, Tenneco, and Honeywell, have in common? Well, not only are they leaders in the automotive renaissance, but they all delivered presentations on leading-edge simulation at the 2014 Automotive Simulation World Congress. Continue reading →
I need to share a story with you that began on the 25th of December, 2013. Every Christmas Day, I wake up very excited to discover what Santa has brought me. But on this particular Christmas, I was extremely disappointed: no present from Santa, even though I sent my letter to the North Pole very early in November. How strange!
(Yes, some friends tell me that he doesn’t exist. I am a serious, grown-up man and, of course, do not believe them — another rumor, that is all.) Continue reading →
Lets talk combustion simulation. I know you dear readers, you are smart! So I will not bore you with explaining what combustion is. Rather, I want to give you some fun facts. As you will see, combustion is really everywhere. Continue reading →
