Heat Transfer by Radiation and Convection From Annular Fins of Trapezoidal Profile on a Cylinder

Abstract

The equations describing steady heat transfer by radiation and convection from annular fins of trapezoidal profile on a cylinder are derived. Mutual irradiation between adjacent fins is considered and the appropriate differential angle factors are presented. A constant convection coefficient is assumed over all surfaces and the fins are treated as gray body radiators. The governing integral equations are approximated by numerical quadrature formulas and the resulting set of non-linear albebraic equations is programmed for solution. A Fortran program listing is included. Some results are obtained for the XM144E1 mortar tube.
