Turbulent flows of practical relevance are often characterized by high Reynolds numbers and solid boundaries. The need to account for flow separation seen in such requires the use (partially) resolving simulation methods on relatively coarse grids. development computational is stagnation. Basically, only a few regularly applied that known suffer from significant shortcomings: uncertainty predic...

In this paper, the MagnetoHydroDynamic (MHD) boundary layer flow over a nonlinear porous stretching sheet is investigated by employing the Homotopy Perturbation Transform Method (HPTM) and the Pade´ approximation. The numerical solution of the governing non-linear problem is developed. Comparison of the present solution is made with the existing solution and excellent agreement is noted. Gr...

in this paper, we consider the variational homotopy perturbation method (vhpm) to obtain an approximate series solution for the generalized fisher’s equation which converges to the exact solution in the region of convergence. comparisons are made among the variational iteration method (vim), the exact solutions and the proposed method. the results reveal that the proposed method is very effectiv...

Abstract A modified collocation method for the numerical solving boundary value problems of mathematical physics is proposed. The irregular arrangement nodes in problem domain can sharply increase accuracy solution by improving quality linear algebraic equations system, to which solved leads. Various basis functions systems are considered. proposed allows one obtain an approximate a wide range ...

The phenomenon of imbibition is great importance in the petroleum industry. In this analysis, we have studied Counter-current through mathematical modelling a double non-miscible phase vertical heterogeneous porous medium, which ensues process oil recovery. non-linear partial differential equation second-order result formulation. Variational iteration approach applied to attain approximate anal...
