Predicting aerodynamic flow physics around automotive vehicles is a complex endeavor, often requiring engineers to balance cost and accuracy. While steady-state approaches (such as RANS) are attractive for their low computational cost, they usually fail to predict all flow phenomena correctly. More fidelity can be achieved using unsteady scale-resolving models such as DES or wall-modeled LES, of course, at a significantly higher cost.

Welcome to this holiday weekend edition of This Week in CFD. For those of you outside the U.S., Monday is Labor Day when we celebrate contributions and achievements of American workers. We do this by not working. But CFD never stops working as evidenced by what’s in today’s issue. Notable are a video of experimental oil flow on a flying wing and an animation of mesh adaptation. This image here (or “this here image” as one might say in Texas) looks like how a tractor-trailer rig might appear to the Predator. I’ve lost the attributions but I’m thinking NASA and the Univ. of Tennessee at Chattanooga were involved.

This week’s digest of CFD news and notes (aka a “link dump” as some have said) begins with a brief stroll down memory lane when 3D CFD of an aircraft was worthy of a press release. For readers who missed the 1980s, we’ve got a video of structured grid generation from that era. After that, there are quite a few applications of CFD from fires to X-Wings to screw compressors. Lots of resources for machine learning are included herein. Plus plenty of webinars, jobs, and financial news. Shown here is an image from a Tecplot case study of liquid jet impingement of nasal irrigation. (Read on for the link.)

This week’s cornucopia of CFD news comes with several reading assignments: 80 years of the finite element method, quantum computing, curves and surfaces, computational simulation, and OpenFOAM book, and cloud PLM among others. Would love to read your thoughts on any of these in the comments. But don’t worry if you’re word-challenged. There are plenty of event news, software releases, and CFD applications that you can skim. Shown here is a beautiful image of two fluids mixing.

It’s Friday and time to get #NavierStoked. (I warned you that I’d steal that.) This week’s theme seems to be food with three food-specific CFD applications including the Application of the Week. (The other applications may be edible but not easily so.) And before delving into all the news, we begin with several articles about workplace culture, promoting STEM via social media, and gamification. Shown here is an illustration of an electron whirlpool, fluid-like behavior in electrons that could be used for future low-power computing. This is something that provides common ground for the Fidelity CFD team (fluids) and the traditional Cadence EDA folks (electrons). [Assuming they have the patience to help me understand the secret lives of electrons.]
