HEAT TRANSFER AND BOUNDARY LAYER FLOW THROUGH A THIN FILM OF HYBRID NANOPARTICLES EMBEDDED IN KEROSENE BASE FLUID PAST AN UNSTEADY STRETCHING SHEET

Abstract

The present work explored the heat transfer and boundary layer flow of a hybrid nanofluid or nanoparticles in an unsteady thin film flow over a stretching sheet. The similarity variables with techniques of the similarity transformations are introduced to reduce the governing equations of partial differential equations (PDEs) systems into a set of an ordinary differential equation (ODEs) system accompanying boundary conditions. The carbon nanotubes with single-wall, SWCNT and the multi-wall, MWCNT in kerosene base fluid are considered. The “bvp4c” function in the MATLAB software is used to solve the reduced form of the mathematical model numerically. The graphs and tables have been generated with the variations of the governing parameter. There exists a strong corelation between findings currently and published results. The rise of the nanoparticle for SWCNT and MWCNT volume fraction increases the local skin friction and the rate of heat transfer, but declines when the flow is decelerated.
