A Numerical Study on Unsteady Natural Convection Flow with Temperature Dependent Thermal Conduct ivity p ast an Isothermal Vertical Cylinder
Journal Title: International Journal of Scientific Research and Management - Year 2015, Vol 3, Issue 7
Abstract
This paper represents a numerical investigation of the effect of temperature dependent thermal conductivity on unsteady natural convection flow past a semi - infinite isothermal vertical cylinder immersed in air. The thermal conductivity is adopted to vary the temperature. The governing non - dimensional b oundary layer equations have been solved numerically employing an explicit finite difference method. To interpret the influence of variable thermal conductivity on the velocity and temperature profiles a parametric study is accomplished. The numerical cons equences disclose that the thermal conductivity has significant influence on transient velocity and temperature profiles, average skin friction coefficient and average heat transfer rate. The conclusion indicates that when the thermal conductivity paramete r increases the temperature and skin friction coefficient increases but the velocity near the wall and Nusselt number decreases. We have also shown the effect of thermal conductivity variation parameter on isotherms and streamlines.
