T1 FREE CONVECTION IN NON-NEWTONIAN POWER-LAW FLUIDS ALONG A VERTICAL PLATE WITH VARIABLE VISCOSITY AND THERMAL STRATIFICATION IN THE PRESENCE OF INTERNAL HEAT GENERATION JF Heat Transfer Research JO HTR YR 2017 FD 2016-11-10 VO 48 IS 1 SP 9 OP 22 K1 free convection K1 thermal stratification K1 non-Newtonian K1 variable viscosity K1 porous medium K1 internal heat generation AB An investigation has been carried out to discuss the effects of variable viscosity and thermal stratification in the presence of internal heat generation on free convection flow along a nonisothermal vertical plate. The plate is semi-infinite and embedded in a porous medium which is saturated with a non-Newtonian power-law fluid. The governing equations of continuity, momentum, and energy are transformed into nonlinear ordinary differential equations using similarity transformations. The Runge−Kutta−Gill method and shooting technique are employed to solve the resulting equations. For the nonisothermal plate, the heat transfer rate increases as θc → 0 for liquids, whereas it decreases for gases as θc → 0 due to the thermal stratification in the presence of internal heat generation. The velocity decreases near the plate and increases away from the plate as θc → 0 for gases. In the case of liquids, the result is reversed. The obtained results are depicted graphically for different parameters involved. PB Begell House LK https://www.dl.begellhouse.com/journals/46784ef93dddff27,293227985b205145,776698cc516a5f0a.html
