Abstract Fluid flow and natural convection heat transfer in a parallelogram enclosure with an inner circular cylinder using Cu-water nanofluid are studied
numerically. Dimensionless Navier-Stokes and energy equations are solved numerically using finite element method based two-dimensional flow and
steady-state conditions. This study evaluates the effect of different concentrations of Cu-water nanofluids (0% to 6%) with different Rayleigh
numbers 103 ≤ Ra ≤ 106 under isotherm wall temperatures. The effects of geometrical parameters of the parallelogram enclosure (inclination angle in
range of 0 ≤ α ≤ 30 and location of inner circular cylinder -0.2 ≤ H ≤… More >
