Effects of chemical reaction and magnetic field on a couple stress fluid over a non-linearly stretching sheet

摘要: The boundary layer flow of an electrically conducting couple stress fluid over a non-linear stretching sheet is investigated in the presence chemical reaction and magnetic field. governing partial differential equations are reduced to coupled ordinary (ODEs) with corresponding appropriate conditions. analytical solutions resulting ODEs have been obtained via homotopy analysis method (HAM) form series, their convergence regions can also be found by control auxiliary parameter. influence pertinent parameters such as magnetic, discussed on velocity concentration profiles fluid. Hence, comparison has made previous results literature limiting case considered problem.
