Dear friends,
I am modeling a gas-solid twophase flow using ASM , in fact in my simulations the solid particles drop at the bottom of pipe very soon and it is clear that the simulation is not correct because when I change the solid density or solid diameter, the simulation does not change , please help me what is the problem ? sincerely |

Are you sure you implemented the different density and diameter correctly? Are you in a flow regime where it is not sensitive to diameter or density? Is your simulation fully converged? Are you interpreting the results correctly?

Dear friend,
In fact yes the simulation is fully converged, but I do not why suddenly the solid particles drop to the bottom of the pipe. Is there any tutorial about ASM model ? sincerely |

You could be in a regime where the density and diameter does nto make much difference, you have to do much larger changes to have an effect.
