Heat and mass transfer associated with a binary liquid droplet immersed in another liquid undergoing rectilinear motion including gravity-and surface tension-induced flows is numerically studied. A full spectral numerical scheme that combines the Galerkin and collocation techniques with orthogonal basis functions is used to solve the governing partial differential equations based on the stream function-vorticity formulation. A liquid-liquid system having similar properties is used as a model problem to illustrate the temporal behaviors of the flow, temperature, and concentration fields. The results indicate that significant differences could exist when the drop is subjected to simultaneous forced convection, free convection, and surface tension-induced convection. Parameters that have been found to control the convective processes are the Reynolds number, the Grashof number, and the Marangoni numbers.
