This week, guest Johannes Wutz from M-Star Center Europe GmbH joins John to discuss turbulence modeling. In this episode, John and Johannes answer the questions: What is a turbulence model? What is RANS and why is it so common? What are the alternatives? What are the industrial implications of better turbulence modeling? "If I have to resort to a RANS simulation, I better get ready to cook up some alphabet soup because I'm going to need to parameterize the heck out of this thing to account for the missing physics that are not captured by these approaches.” – John Thomas Questions about turbulence models?
