Temperature-Dependent Heat Sources and Sinks in a Stagnation-Point Flow under Transverse Magnetic Field

Abstract

Heat transfer in stagnation-point flow of an electrically conducting viscous fluid in the presence of a transverse magnetic field and temperature-dependent sources or sinks, has been studied. Composite series for the heat generation or removal parameter β have been constructed with the help of asymptotic-fit method of Rosenzweig. Ratio of heat transfer with and without magnetic field has been calculated by using Bush’s data and also the assumption of Neuringer and Mcllroy for the inviscid flow. It is found that the presence of magnetic field decreases the heat transfer.
