NATURAL CONVECTION FROM A HORIZONTAL CYLINDER AT MODERATE GRASHOF NUMBERS,

Abstract:

At moderate Grashof numbers, significant departures from the predictions of boundary-layer analysis are found in the flow and heat transfer from a heated horizontal cylinder. The departures can be analyzed if the full Navier-Stokes equations are used in the formulation of the problem. A set of solutions is presented for the basic pair of simultaneous differential equations for natural convection on a horizontal cylinder for a Prandtl number of 0.72. The solution is compared with experiments for a Grashof number of about 1000, and found to be in good agreement. Author
