Abstract An unsteady numerical model for double-diffusive natural convection of low Prandtl number liquids with Soret and Dufour effects inside the horizontal
cavity is developed. The thermosolutal model is solved numerically using the SIMPLE algorithm with QUICK scheme. The flow field, temperature
and concentration distributions for different buoyancy ratios, Rayleigh numbers and aspect ratios under different Prandtl numbers are studied
systematically. The results reveal that the flow structure develops from conduction-dominated to convection as buoyancy ratio increases under different
Prandtl numbers. Heat transfer intensity keeps constant and mass transfer intensity grows slowly before a critical point More >
