Hello,
i'm an Ansys newbie and need help. For my masterthesis i have to do a numerical Simulation for a given aerospike nozzle in diffrent altitudes. I have two inlets, the first one for the surrounding Air and the second one is the outlet opening of the combustion chamber ( the fuel is water or rather the steam). The other components are opening, outlet, aerospike(wall). So how can i handle two inlets with two diffrent materials? Do i have still one domain and what are the settings for the bounderies for the inlet of the aerospike. I have the required mass flow for the nozzle and the exact informations about the fuel ( evaporation degree, temperature, pressure). You can find a screenshot from my actually setup. Thanks for your help. Would be great and sorry for my bad english. Greetings Lucas |

First of all - why not model this as 2D axisymmetric?
The two different materials are either a multicomponent or a multiphase model. If the fluids are air and steam then you only have a single phase so this is a multi component mixture.

We hear "my prof told me to do it that way" many times on the forum. Take it from me, that you should develop a complex model like this using the simplest geometry which is representative, and this is a 2D axisymmetric geometry. If you need 3D geometry to add some 3D features then you should do that later, after you have developed the basic numerical approach on a 2D model.
