On Modified Algorithm for Fourth-Grade Fluid

الملخص EN

This paper shows the analysis of the thin film flow of fourth-grade fluid on the outer side of a vertical cylinder.

Solution of the governing nonlinear equation is obtained by Rational Homotopy Perturbation Method (RHPM); comparison with exact solution reflects the reliability of the method.

Analysis shows that this method is reliable for even high nonlinearity.

Graphs and tables strengthen the idea.
