SHARMA, P. K.. Fluctuating thermal and mass diffusion on unsteady free convection flow past a vertical plate in slip-flow regime. Lat. Am. appl. res. [online]. 2005, vol.35, n.4, pp.313-319. ISSN 0327-0793.

The unsteady free convective viscous incompressible flow past an infinite vertical porous flat plate with periodic heat and mass transfer in slip-flow regime is discussed. Assuming variable suction at the porous plate, approximate solutions are obtained for velocity, skin-friction, temper-ature, heat transfer and species concentration. During the course of discussion, the effects of Gr (Grashof number based on temperature), Gc (modified Grashof number based on concentration difference), Sc (Schmidt number), A (suction parameter) and ω (frequency) for Pr=0.71 (air) have been presented.
