i have some problems in simulating a fluid dynamics problem.. a tank is filled with fuel. then there is an injector injecting the same fuel but with a different density into the tank. the injector is immersed under the existing fuel level in the tank. we want to measure the distance the injector can inject the fuel into the tank filled with fuel of a different density. i have tried before this..but i can't use the same material but with 2 different density. how do i go about this problem??

i thank you in advance.

Hi!

You should work with multiphase model. Probabilly mixture model will work good for you, and if not then try Euler multiphase model.
