摘要
The effect of sinusoidal heating on double-diffusive mixed convective flow with heat and mass transfer in a lid-driven square cavity is numerically investigated. The horizontal walls of the cavity are adiabatic and impermeable. Sinusoidal boundary temperatures and concentrations are imposed along the left and right sidewalls of the cavity. The governing unsteady equations for continuity, momentum, energy and species transfer are solved using the finite-volume method. The numerical solutions are computed for various parameters such as the Richardson number, amplitude ratio, buoyancy ratio and phase deviation. The obtained results are discussed in detail under different combinations of the pertinent parameters.
