OPTIMAL HOMOTOPY ASYMPTOTIC METHOD SOLUTION OF UNSTEADY SECOND GRADE FLUID IN WIRE COATING ANALYSIS
REHAN ALI SHAH,S. ISLAM,A. M. SIDDIQUI,T. HAROON 한국산업응용수학회 2011 Journal of the Korean Society for Industrial and A Vol.15 No.3
In the present work, the mathematical model of wire coating in a straight annular die is developed for unsteady second grade fluid in the form of partial differential equation. The Optimal Homotopy Asymptotic Method (OHAM) is applied for obtaining the solution of the model problem.. This method provides us a suitable way to control the convergence of the series solution using the auxiliary constants which are optimally determined.
