| Popis: | Mixed convective energy transport of a hybrid nanosuspension (MWCNT-Fe3O4/H2O) within a heated/cooled lid-driven chamber with an oscillation velocity of the moving lid was computationally scrutinized. Non-dimensional control equations written employing the conservation laws and non-primitive variables were solved by the finite difference technique. The developed programming code was verified using the mesh sensitivity analysis and computational results of other researchers. The influence of the Reynolds number, nanoadditives volume fraction and velocity oscillation parameter on flow structures, temperature patterns, mean Nusselt number and nanosuspension flow strength was analyzed. More essential energy transference augmentation with solid particles concentration was found for high Reynolds numbers (forced convection mode), while for low and moderate Reynolds numbers such an enhancement was weak. |
