ABSTRACT An overview of recent works on mass and heat transport in a dilute binary mixture under steady shear flow is presented. The physical situation is such that an arbitrary shear rate coexists with a weak concentration gradient. Under these conditions mass and heat transport are induced in the system and the relevant transport coefficients are explicitly obtained. The analysis is made following a perturbation solution in powers of the concentration gradient but taking the steady shear flow as the reference state. In the first order of the expansion the results show that the mass and heat fluxes are proportional to the concentration gradient but, due to the anisotropy of the problem, mutual diffusion and Dufour tensors are identified, respectively. Both tensors are explicitly determined in terms of the shear rate and the parameters of the mixture (particles masses, concentrations, and force constants).
