The surface temperature 7, and free stream temperature To. Consider physical properties are varied with the temperature as k Ho Ko .) . where a, b, and c are constant. The equations governing the fluid motion and the temperature field are: Continuity a(u) a(v) -=0 dx Momentum du du d pu + pv dx dy Energy OT OT -+ pcv ax dy K = With the boundary conditions: at y = Q u= v=0, T=To as y - c u - un and T - To Obtain the equations governing the similarity solution for the stream function and the temperature field. For the temperature of 600 to 2400 "F, the physical properties can be approximated with a = 0.7, b = 0.19 and c = 0.85 and Pro = 0.7. Plot w/u. and T/To for To/To = 1.5,2,3 and 5. With Cy and Nu are the local skin friction coefficient and Nusselt number when the properties are variable and Crep Nucp are the local skin friction coefficient and Nu Nusselt number when properties are constant, plot -and NUCP - vs To/Ta. Nu Approximative Cecr and , find the m and n values for the NUCP best fit to these approximations
