Hello , I'm using Fluentv5 to model ceramics particles in-flight in thermal spraying. I'm using the two ways coupling but I don't see any influence on my continuous phase and I know I should. Is there any minimum mass flow of discrete phase to enable the two ways coupling?

Thanks for help

Dear Alice

Continuouse phase hardly affected by discrete phase if solid mass flow rate is less than 20% of gas mass flow rate. So, in general, when SOLID_mas/GAS_mas (ratio of mass flow rate) is less than 0.2, one way coupling may be applicable.

Thanks a lot for informations
