A numerical algorithm is presented for studyinglaminar convection flow andheat transferat the lower stagnation point of a solid sphere.By means of similaritytransformation, the original nonlinear partial differential equations of flow aretransformed to a pair of nonlinear ordinary differential equations. Subsequently theyare reduced to a first order system and integrated using Newton Raphson andadaptiveRunge-Kutta methods.The computer codes are developedfor this numerical analysis inMatlab environment. Velocity and temperature profiles for various values of Prandtlnumber and at a fixed conjugate parameter are illustrated graphically. The results ofthe present simulation are then compared with previousresults available in literaturewith good agreement.Refference:
