Computational Analysis of MHD Copper-Water Nanofluid with effect of Viscous Dissipation & Thermal Radiation over Isothermal Moving Sheet

Abstract

The study has examined the flow of Cu-H2O nanofluid over an isothermal moving sheet subjected to the influence of viscous dissipation, thermal radiation and a vertical magnetic field. The fundamental partial differential equations have been transformed into a system of ordinary differential equations through the application of similarity transformation. The MATLAB tool ‘bvp4c’ has been employed to solve dimensionless ordinary differential equations to get numerical results. The effects of emerging parameters say velocity and temperature profiles have been depicted through graphs. With increase in volume fraction of particles, it shows an increasing tendency in the velocity curves for both the particle shapes taken. The pronounced elevation in temperature, driven by an increase in viscous dissipation (higher Eckart number) and platelet shape produces much higher temperature than spherical shapes. The values for Nusselt number for platelet shape exceeds the values of spherical shape particles. This work has applications in nanofluid-based cooling systems, thermal energy storage, magnetic field control, etc.
