EFFECT OF MARANGONI CONVECTION ON UNSTEADY SQUEEZED FLOW OF WATER BASE CNTS NANOFLUID IN THE PRESENCE OF MAGNETIC FIELD AND VARIABLE THERMAL CONDUCTIVITY OVER A STRETCHING SURFACE

Abstract

This research paper explains the effect of Marangoni convection on unsteady squeezing flow of water base CNTs for both MWCNT and SWCNT in the presence of magnetic field and variable thermal conductivity over a stretching surface. By using the similarity transformation, the partial differential equation is converted to nonlinear fourth order ordinary differential equations. The analytical method, namely Optimal Homotopic Analysis Method used to find the analytical solution of the nonlinear problem which analyze the problem. The result of important parameters for both velocity and temperature profiles are plotted and discussed. The BVPh 2.0 package is used to obtain the convergence of the problem up to 25 iteration. The skin friction coefficient and Nusselt number is explained in table form.
