Dear Engineers & Engineering students,

With the advent of SpaceX's Falcon Heavy Launch, there is no better time to release this video!

If you are interested in simulations of rocket engine nozzles, this video is for you.

I teach you how to perform a detailed CFD (fluid dynamics), FEA (structural analysis) as well as combined thermo-structural interactions. This means taking the load from a CFD simulation and importing it into the structural analysis. Pressure loads are also applied using isentropic flow relations for a rocket nozzle. Multiple ANSYS tools are required to carry out the simulation namely:

1) Face Split
2) Geometry Slicing
3) MultiZone meshing

A pre-stressed harmonic analysis is also performed here. A harmonic load is simply a load which is time-dependant (i.e. acceleration with a frequency). You can see an example of harmonic loading from the SpaceX Falcon 9 User's Manual (in the Environment section).

I hope you learn something new in ANSYS from this video!

Best Wishes
