Abstract
Abstract We present a research for Marangoni convection heat transfer in power law nanofluids driven by temperature gradient. Four types of nanoparticles, namely Cu, Al2O3, CuO and TiO2 are considered by using power law CMC-water as a base fluid. The effects of power law viscosity on temperature field are taken into account by assuming that the temperature field is similar to the velocity field and the surface tension is assumed a quadratic function of the temperature. The governing partial differential equations are formulated and similarity solutions are obtained numerically using shooting method. The effects of the solid volume fraction, the Power law index and the Marangoni parameter on the velocity and temperature fields are analyzed and discussed in detail.
