RT Journal Article ID 767de30f4825ad40 A1 Sharma, Kalpna A1 Gupta, Sumit T1 RADIATION EFFECTS ON MHD BOUNDARY LAYER FLOW AND HEAT TRANSFER ALONG A STRETCHING CYLINDER WITH VARIABLE THERMAL CONDUCTIVITY IN A POROUS MEDIUM JF Journal of Porous Media JO JPM YR 2018 FD 2018-07-16 VO 21 IS 8 SP 763 OP 779 K1 MHD flow K1 HAM K1 porous medium K1 thermal conductivity K1 radiation AB This study considers MHD boundary layer flow and heat transfer of a viscous incompressible fluid over a radiative stretching cylinder with variable thermal conductivity embedded in a porous medium. Using similarity transformation, the nonlinear partial differential equations of momentum and heat transfer are converted into nonlinear ordinary differential equations which are then solved by the homotopy analysis method (HAM). The effects of significant physical parameters on the velocity and temperature are investigated and discussed graphically. The obtained results are also compared with known results and are found to be in excellent agreement.
