Flows along a symmetric slotted wedge and heat transfer

In the present paper the forced convection flow of a viscous incompressible fluid past a uniformly heated slotted wedge has been investigated numerically. The equations governing the flow and heat transfer are reduced to local similarity equations, treating ξ βx/Rex2, where Re, is the local Reynolds number) as a local slip variable. The transformed boundary-layer equations are solved numerically using implicit finite difference method for all values of ξ in the interval 0,104. The solutions are also obtained for smaller values of ξ using the perturbation method. Further transformed equations has also been obtained appropriate for large values of ξ, which then have been integrated by the well established local nonsimilarity method. The asymptotic solutions for both smaller and larger values of ξ, obtained in terms of the local skin-friction and local rate of heat transfer for different pressure gradient m, are found in excellent agreement with that obtained by the finite difference solutions for all ξ.
