Heat transfer and nanofluid flow of free convection in a quarter cylinder channel considering nanoparticle shape effect
The finite volume method is employed to analyze the fluid flow, heat transfer and entropy generation within a fluid channel. The fluid channel is filled with CuO-water nanofluid. The KKL model is used to estimate the dynamic viscosity and consider the Brownian motion. On the other hand, the influence of nanoparticles' shapes on the thermal conductivity is considered. The fluid channel is included with hot and cold fluid injection pipes which are modeled as active bodies in 2D model. Three different governing parameters are utilized such as Rayleigh number in range of 10(3) < Ra < 10(6), nanoparticle concentration in range of 0
