Abstract :
In this paper, mixed convection fluid flow, heat transfer and entropy generation inside a triangular enclosure filled with CuO-water nanofluid with variable properties are investigated numerically. The inclined walls of enclosure are maintained at a constant temperature Tc. The moving bottom wall is kept at a constant temperature Th, which Th>Tc.The numerical simulation of mixed convection is carried out using a computer program (FORTRAN language) based on finite volume method and SIMPLER algorithm. This study is performed over a range of nanoparticle volume fractions(0-0.02-0.04) Richardson numbers(0.01, 0.1, 1, 10, 100), and angles of inclined walls(150, 300, 450, 600, 750) and a fixed Grashof number (Gr=104).In all investigated aspect ratios and Richardson numbers, average Nusselt number increased by enhancement of volume fraction till 0.02, but it is approximately constant by adding more nanoparticles till 0.04.It is also observed that in all aspect ratios and Richardson numbers, the variation of total entropy generation by enhancement of volume fraction is similar to Nusselt number.
