Numerical Analysis of Fluid Flow Due To Free Convection In a Lid-drIven Cavity Having a Heated Circular Hollow Cylinder”

Abstract

Free convection heat transfer induced by the combined effect of mechanically driven lid and buoyancy force in a circular hollow cylinder. In the enclosure, the horizontal walls are maintained an uniform temperature at any point. The present study simulates a realistic system such as heat transfer in heated boiler cell. The governing equations for the problem are firstly transformed into non-dimensional form. The computation carried out with Grashof and Rayleigh number. The analysis is transmitted with the variation of streamlines and isothermals for different Rayleigh number ranging from where Prandtl number kept 0.71 constant. Moreover, the results of this investigation are shown by the variation of fluid temperature in the enclosure with the different perimeters (velocity, Pressure
