Hello Dear researchers.I am conducting a numerical simulation for a heat transfer enhancement of double pipe heat exchanger using nanofluids.However,I do have a doubt.Can CFD Ansys Fluent be used as an appropriate tool to analyze the nanofluids(nanoparticles dispersed in base fluids) problem?.If yes,then ,how can the effects of nanoparticles come in to play while using the software?.Is it just through the effective thermophysical properties that we get from existing correlations,Or Is there some kind of flow physics ?.I would appreciate your kind help.Thanking in advance
