A Brief Survey of Preparation and Heat Transfer Enhancement of Hybrid Nanofluids

Abstract

Investigation of domestic application of heat flux dissemination is in incredible request. The best strategy in getting the coolant with an ideal execution is by including particular sorts of nanoparticles to the base fluid. The utilize of nanofluids is to escalate heat transfer coefficient through the enhancement of base fluid’s thermal conductivity. An advanced coolant (Hybrid nanofluid) was delivered by blending two or more different types of nano size particles with conventional fluid. This article mainly aims to cover the recent publications in hybrid nanofluids on different aspects such as preparation, thermophysical properties, and heat transfer enhancement. In common, the culminate combination of different nanoparticle properties results in an excellent thermal conductivity and heat transfer coefficient improvement were reached up to 148% compared to the base fluid. Moreover, moderate increase on pressure drop has been detected due to presence of composite nanoparticles. In any case, the anticipated results for both thermal conductivity and viscosity values utilizing classical relationships were distinctive from the experimental results.
