Numerical comparison of viscosity models on mixed convection in double lid-driven cavity utilized CuO-water nanofluid

摘要: Laminar incompressible mixed-convective heat transfer in 2-D lid-driven cavity, filled with nanofluid CuO-water, is studied numerically. Eight different viscosity models are compared to investigate the enhancement and increase average Nusselt number. The point of view each model essentially differs terms whether it takes various parameters such as temperature effects, Brownian motion nanoparticles, radii aggregated particles, volume-fraction nanoparticles into account or not. governing stream-vorticity equations solved using a second order central finite difference scheme, coupled conservation mass energy. main sensitive interest chosen volume fraction Richardson performance study interpretation corresponding results velocity components done range
