Experimental and theoretical analyses of the boundary layer development and the heat transfer coefficients in various thermally simulated components have been carried out for both forced and free convection con
Later, Mazumder and Dandapat [23] considered a generalized model of convection-diffusion equation in a combined free and forced convective channel flow and evaluated diffusion coefficients along the longitudinal direction of the channel. They found that this coefficient is valid for all time after ...
In this paper the heat transfer by free and forced convection in a ventilated cavity is studied. The cavity is used to model a room, where a wall is receiving a uniform heat flux (like the one supplied by sun). In order to obtain the numerical results, the CFD's software Fluent 6.3 ...
This article examines the effects of magnetohydrodynamics and heat absorption on an incompressible Jeffrey fluid’ time-dependent free convection flow over an infinite, vertically heated plate with homogeneous heat flux. The constitutive equation for hea
