Abstract
a two-equation model has been adopted in obtaining numerical solution of turbulent natural from an isothermal horizontal circular cylinder The k-e model employed in this study characterizes turbulence through the kinetic energy and its volumetric rate of dissipation The transport equations for these two variables, along those for time - averaged stream function, vorticity, and temperature, form a closed set of five coupled partial differential equations These equations are solved for the entire flow domain, without boundary layer approximations.
