Start-Up and Pre-Analysis — Lesson 2

This lesson covers the pre-analysis for compressible flow in a nozzle using Ansys Fluent® fluid simulation software. The instructor, Will Cully from Cornell University, explains the process of analyzing a converging-diverging nozzle with given pressure conditions at the inlet and outlet. The lesson delves into the mathematical model, including governing equations and boundary conditions, and the numerical solution strategy. The lesson also discusses the assumptions made for the analysis, such as axisymmetric, steady, inviscid, and ideal gas assumptions. The lesson concludes with a comparison of the numerical approach to an analytical case.
