Abstract

The problem of Marangoni heat transfer boundary layer flow using water based nanofluid containing nanoparticles including Ag, Cu, Al2O3 and TiO2 embedded in a variable viscosity & thermal conductivity medium is analyzed. The governing boundary layer equations (momentum and thermal boundary) are transformed into nonlinear ordinary differential equations by using the appropriate similarity transformations and were solved by using Maple software.
Solution of the governing equations are presented for different values of the governing parameter such as the effect of nanoparticle volume fractions, viscosity parameter and conductivity parameter to demonstrate the important influence of these parameters in terms of velocity and temperature as well as surface gradient velocity and temperature gradient.
