Mohamed  studied unsteady MHD flow over a vertical moving porous plate with heat generation and Soret effect.
To the best of our knowledge, considerably less work has been done concerning the combined effect of Hall current and Soret effect on chemically reactive magnetomicropolar fluid flow incorporating the effect of rotation in slip flow regime in the presence of radiation and heat absorption.
Many studies concerning the relevance of double diffusive convection in porous enclosures were performed, but Soret effect
was seldom taken into account in such medium in the HRL configuration.
Sreevani  has analyzed the Soret effect
on convective heat and mass transfer flow of a viscous fluid in a cylindrical annulus with heat generating sources.
In the microgravity environment of space, the diffusion coefficients of the different oil components are constant and the Soret effect
is the main factor affecting oil dispersion.
Sattar and Alam  studied the effect of free convection and mass transfer flow past an accelerated vertical porous plate, taking into account of Soret effect
When heat and mass transfer occur simultaneously in a moving fluid affecting each other causes a cross diffusion effect, the mass transfer caused by temperature gradient is called the Soret effect
, while the heat transfer caused by concentration effect is called the Dufour effect.
Thermal-diffusion known as the Soret effect
takes place and as a result a mass fraction distribution is established in the liquid layer.

In view of the importance of this diffusion-thermo effect, Jha and Singh  presented an analytical study for free convection and mass transfer flow past an infinite vertical plate moving impulsively in its own plane taking Soret effects
