Abstract
The present paper is concerned with the study of MHD free convective flow of a visco-elastic (Kuvshinski type) dusty gas through a porous medium induced by the motion of a semi-infinite flat plate under the influence of radiative heat transfer moving with velocity decreasing exponentially with time. The expressions for velocity distribution of a dusty gas and dust particles, concentration profile and temperature field are obtained. The effect of Schmidt number (Sc), Magnetic field parameter (M) and Radiation parameter (N) on velocity distribution of dusty gas and dust particles, concentration and temperature distribution are discussed graphically.

The present note is the study of MHD free convection flow of a visco-elastic (KUVSHINISKI TYPE) dusty gas through a semi infinite plate moving with velocity decreasing exponentially with time and radiative heat transfer under the same conditions and assumptions taken by Varshney and Prakash.[12]
Let the dusty gas to confine in the space y>0 and the flow is produced by the motion of a semi – infinite flat plate moving with velocity νe−λ2t in x-direction
Summary
The study of radiation in thermal engineering is of great interest for industry point of view. Makinde and Mhone[15] have investigated the combined effect of a transverse magnetic field and radiative heat transfer to unsteady flow of a conducting optically thin fluid through a channel of non-uniform wall temperature filled with saturated porous medium. Varshney and Prakash[12] have discussed MHD free convection flow of a visco elastic dusty gas through a porous medium induced by the motion of a semi- infinite flat plate moving with velocity decreasing exponentially with time. The present note is the study of MHD free convection flow of a visco-elastic (KUVSHINISKI TYPE) dusty gas through a semi infinite plate moving with velocity decreasing exponentially with time and radiative heat transfer under the same conditions and assumptions taken by Varshney and Prakash.[12] The expressions for concentration profile, temperature field and velocity distribution for both dusty fluid (gas) and dust particles are derived
