摘要：

In this study the influence of Brownian motion models on fluid-flow, heat transfer, and entropy generation in nanofluid forced convection with variable properties has been numerically inspected in a enclosure with central heat source. The governing equations were solved by finite volume method and SIMPLER algorithm. The numerical study was carried out for Reynolds numbers between 10 and 1000 and nanoparticles volume fraction between 0 and 0.04. The numerical results show that for all investigated models the average Nusselt number increases by nanoparticle volume fraction increment in all Reynolds number. The overall entropy generation behavior is similar to average Nusselt number variation for all inspected models. Among all analyzed models the estimation of Maxwell-Brinkman and Das-Vajjha are mainly closed to each other.
