A kutatási téma leírása:
The problem of the MHD boundary layer flow of power law non-Newtonian fluids with various boundary conditions will be studied. Similarity transformations are possible for momentum and heat equation of viscous fluids. Under appropriate assumptions, partial differential equations are transformed into an autonomous third-order nonlinear degenerate ordinary differential equation with boundary conditions. Using a shooting method the skin friction parameters, which are found to depend on the values of the power law index n. it is involved in the drag coefficient,, velocity and thermal properties are examined. Some solutions will be presented graphically to illustrate the results and the behaviors of the solutions.
