摘要
An investigation and analysis have been made for the magnetohydrodynamic (MHD) nonlinear convective flow of Oldroyd-B fluid in the presence of a non-Darcy porous medium. Thermal radiation, mixed convection, and heat generation/absorption are present. Features of heat transfer are studied in view of convective surface conditions. Implementation of suitable variables yields nonlinear ordinary differential systems. Resulting systems have been solved through a homotopic procedure. The characteristics of different physical quantities on velocity and temperature are scrutinized graphically and deliberated physically. The expression of the local Nusselt number is calculated and explored through numerical values. Temperature and rate of heat transfer are enhanced when the thermal radiation parameter and Biot number are increased.
