Non-Uniform Heat Source/Sink and Thermal Radiation Effects on the Stretched Flow of Cylinder in a Thermally Stratified Medium

Abstract

The paper addresses the influence of non-uniform heat source/sink in flow of couple stress fluid by a stretching cylinder in a thermally stratified medium. Thermal radiation effect in heat transfer analysis is also accounted. Conservation laws of mass, linear momentum and energy leads to nonlinear situation. Use of adequate transformations coverts the partial differential equations into the ordinary differential equations. Series solutions of the resulting equations are obtained for the velocity and temperature. Convergence of the solutions is explicitly checked. Impacts of various sundry variable son the velocity, temperature, wall shear stress and Nusselt number are examined through graphical illustrations and numerical values. The effect of β and Re on velocity field is qualitatively similar. For larger values of curvature parameter γ velocity enhances. Influences of S and R on temperature on the temperature distribution are opposite. Heat transfer at the surface decays when A and B increase.

Effect of Non-Linear Radiation and Non-Uniform Heat Source/Sink on Flow over a Linear Stretching Sheet with Fluid Particle Suspension

“…The analysis of numerical solutions has been done for the effect of various physical parameters like radiation parameter (Ra), Prandlt Number (Pr), Particle interaction parameter (𝛽), Eckert Number (Ec) etc. The results are also matched with the results available in previous literature [4,6,17]. Here the values of rate of heat transfer are matched with the previous authors.…”

“…So many researchers have conducted their work on the boundary layer flow with effect of radiation and non-uniform heat source/sink on linearly stretching surface. THayat [6] introduced the effect of thermal radiation and non-uniform heat source/sink in a fluid which passed over a stretched cylinder. Krishnaiah [7] numerically analyzed the result of non-uniform heat source/sink on stagnation point flow of MHD fluid which passed on an exponential stretched sheet.…”
