Abstract

This research article numerically studies the influences of an effective Prandtl number along with magnetic field on the melting heat transport characteristics of Ethylene glycol/Water with gamma Al 2 O 3 nanoparticles over a stretching sheet. To analyse the impacts of effective Prandtl number, the non-dimensional melting heat transfer boundary conditions are derived for the first time with and without effective Prandtl number. A non-linear form of thermal radiation is used. The experimental based thermo-physical properties of gamma Al 2 O 3 nanofluids are considered. The electric conductivities of Al 2 O 3 , water and ethylene glycol are used to calculate of effective electric conductivity to study the magnetic field effects. Mathematical models are developed and solved by numerical technique based on the Iterative Power Series (IPS) method with shooting strategy. The numerical outcomes are discussed through plots and tables.
