چکیده انگلیسی
This work assess the effectiveness of the pulsating flow regime for the enhancement of heat and mass transfer in double diffusive problems by studying a two-dimensional, heated, lid cavity. The research characterizes the influence of pulsating parameters such as temporal frequency, wave number and amplitude in the process. Results show that the pulsating regime enhances heat/mass transfer within a square cavity up to a 14%/38% respectively with respect to the non-pulsating case, due to the promotion of additional shear stress fields. As Richardson number, Brownian diffusion or the solute/thermal buoyancy ratio increase or the cavity becomes narrower, heat/mass transfer increases.
