Carreau fluid is a type of generalized Newtonian fluid where viscosity depends upon the shear rate of the fluid and then uses it to obtain a formulation for the boundary layer equations of the Carreau fluid. The objective of the present study is to analyze the development of the slip effect on the MHD stagnation-point flow of Carreau fluid past a shrinking sheet. The mathematical modeling of Carreau fluid has been developed for boundary layer problem and the governing partial differential

The effect of velocity slip is taken into account and controlled by non-dimensional parameter. The dual solutions are obtained when the sheet is shrunk. The study shows that the skin friction decreases with an increase in velocity slip.
