Natural Convection Heat Transfer From a Horizontal Circular Cylinder With Constant Surface Heat Flux

This work analyses the natural convective heat transfer from a horizontal circular cylinder with constant surface heat flux using radial equally spaced exterior low conductivity baffles. The dimensionless governing equations in the stream function–vorticity formulation were solved using the finite difference method. The influence of the system parameters, the number of baffles and the baffle height, on the average Nusselt number is presented.
