An exact solution to the one-dimensional unsteady natural convection flow past an impulsively started infinite vertical plate with combined effect of thermal stratification and radiation under the influence of transverse magnetic field is presented. The solutions for fluid velocity, temperature are obtained by the Laplace transformation technique. Comparison is made between the solutions with and without thermal stratification and the differences in both the cases are presented graphically. Comparison reveals that thermal stratification has significant impact on convection flow past vertical plates on radiating MHD flows.

Unsteady Natural Convection

PurposeThe purpose of this paper is to deal with an unsteady natural convection flow of a rotating fluid past an exponential accelerated vertical plate. The effect of Hall current, ion-slip and magnetic field is considered. Two types of plate temperature, namely, uniform and ramped temperature are considered to model heat transfer analysis.Design/methodology/approachThe Laplace transform technique is employed to find the closed form solutions for velocity, temperature and concentration.FindingsThe effects of flow governing parameters on the velocity profile, temperature profile, concentration profile, skin friction, Nusselt and Sherwood numbers are discussed and presented through graphs and tables. It is found that fluid velocity in the primary flow direction decreases with the increase in the magnetic parameter.Originality/valueFirst time in the literature, the authors obtained closed form solution to natural convection flow of a rotating fluid past an exponential accelerated vertical plate.
