I am currently doing Nano fluids simulation in Ansys-fluent and i am struck at the point where i am unable to model the flow using Discrete phase model (base fluid is primary phase and nano particles as injections) and Eulerian-Eulerian (Base fluid as primary phase and nano particles as secondary phase) model. Using mixture model i was able to simulate and get the results which i correlated with the literature available (I. Behroyan et al.)
