The effect of solid volume fraction on convective flow inside a prismatic cavity is analyzed numerically. The water-based Cu and CuO nanofluids are used as the working fluids inside the cavity. This work investigates the comparative performance between these two nanofluids. The governing differential equations with boundary conditions are solved by Finite Element Method using Galerkin’s weighted residual scheme. The behavior of parameter related to performance such as temperature, velocity distributions, convective heat transfer, mean bulk temperature and magnitude of subdomain mean velocity areexamined systematically. This parameter includes the solid volume fraction . The results show that the performance of the cavity can be improved by using the largest . Higher heat transfer rate is obtained using water/Cu nanofluid. Magnitude of mean velocity becomes superior for water/CuO nanofluid than water/Cu nanofluid.
