Podcast Recorded: October 20th, 2023
Dr. Akshai K. Runchal has over 50 years of experience in CFD and simulation of flow, heat and mass transport processes in engineering and environmental sciences, He obtained his Ph.D. in 1969 from Imperial College (London) under the guidance of Prof. D, B. Spalding. He was a key member of the 3-person team led by Spalding that invented the Finite Volume Method (FVM) of Fluid Dynamics (CFD) in mid 1960's. He started his professional career as a faculty at IIT Kanpur in 1969 and has also taught as regular or adjunct faculty at Imperial College (London), University of California (Los Angeles), Cal Tech (Pasadena), and Cal State (Northridge). In 1979, Dr. Runchal established the ACRi group of companies that has offices in Los Angeles (USA), Nice (France) and Bangalore (India).
For the past 50 years, Dr Runchal, has consulted extensively on projects related to flow, heat and mass transfer, combustion, environmental impact, management of air, surface and ground water resources, safe disposal of hazardous and nuclear waste, and, policy and decision analysis. Dr. Runchal is a co-author of the first book ever published on CFD. He is the author or co-author of 12 books and over 200 technical publications. He is the principal author of the ANSWER®, PORFLOW®, TIDAL®, and RADM™ CFD Software Tools that are widely employed by commercial, academic, and R&D organizati

AMAZING KADE; I have no other words !! The way Saplding spotted the problem, "Parabolic equation has no diffusion that propagates upstream." That is accurate, but imagine when they were learning and developing all that knowledge. It may be common sense today but look at it from the eyes of the people developing all this... I worked on parabolized Navier Stokes Equations at the beginning of my PhD and it struck me the simplicity and its resolving power simultaneously! That reminds me about the elliptic nature of disturbance in the BL; I remember I had a discussion with a lecturer many years ago about the nature of signals that trigger transition !! AMAZING !!

That episode was amazing! The creativity of the CFD developers in using pure physics to describe complex phenomena is truly inspiring. Thank you very much!
-
I enjoyed our discussion very much. For the next sessions, I recommend that 1. It would be great to have an expert working on CFD and AI (ML) together, most likely on flow past over airfoils, cylinders, etc., 2. CFD and parallel computation Thank you.

I think what resonated with me was the distinction between being a scientist and an engineer. Which is the difference between good enough to solve problems vs state of the art accuracy. Sometimes there can be frustration from CAE simulation engineers in small teams dealing with both method development and production pipelines, that designers do not care enough to understand the physics and limitations behind the insights given to them, they just expect an answer of go/no-go. When designs have less margins due to cost and efficiency reasons, models which were previously sufficiently accurate suddenly need improvement and this is where engineers need to put on scientist hats to figure things out. I think ability to adapt to this role switch is important to have in a career in this field.

That's it what I am looking for in this platform. Thanks for this content ❤love from India🇮🇳

Great podcast. I feel very related with the research hat and consulting hat in CFD project ^^
-
Really insightful words from Dr. Akshai Runchal. Thanks for sharing Kade

Hey dear. I saw your YouTube channel. Your channel has many videos but not enough views and subscribers. Your channel should be optimized, your videos are very good but your video optimization is very bad Example: SEO score is zero, no perfect title - description - no SEO friendly tags added, no social media sharing Platform and some in your YouTube channel Settings are not correct. Because of this your video is not reaching the people who are interested and you are not getting enough views, likes and subscriptions Many problems for which your video views and subscribers are not good. As a result, your video views are not affected. You need SEO for your YouTube channel immediately. As a video SEO expert, I look forward to your response. Thank you.
