A comprehensive study of two-phase flow and heat transfer of water/Ag nanofluid in an elliptical curved minichannel

In this research, laminar flow and heat transfer of two-phase water/Ag nanofluid with 0–6% volume fraction of nanoparticles at Re = 150–700 in a curved geometry are simulated using finite volume method. Studied geometry is an elliptical curved minichannel with curvature angle of 180°. Forced and natural flow of two-phase nanofluid is simulated at Gr = 15000, 35000 and 75000. For estimation of nanofluid flow behavior, two-phase mixture method is...
