Application of CFD to Advance Thermal Management of Aerospace Systems

Though CFD has come a long way and widely used in industry, it is still “Colorful and Fancy Display” and “Constant Frustration and Disappointment” to many. Also, the following anonymous quote is still true: “No one believes the simulation except who did it! Everyone believes the test results except who did it!” If you do not believe this quote, just try to publish a paper that uses CFD to solve a science or engineering problem without experimental validation. Since experimental studies typically do not get the same scrutiny on verification and validation of their methods, this talk gives examples in heat transfer where CFD shows experimental studies could yield solutions that are wrong or provide incorrect guidance on design. Since AI is now vogue, where many researchers use machine learning tools to study engineering and science problems, some observations are made.
