A one-dimensional numerical solution is obtained for the steady-state thermal behavior of annular fins of trapezoidal profile which transfer heat by conduction and radiation. The results obtained are presented as charts relating fin efficiency to the dimensionless group (rT − rB )εσTB3/k cos α, for various values of the dimensionless groups rB /(rT − rB ), ZT /(rT − rB ), and arctan [(ZB − ZT )/(rT − rB )]. As presented the problem is the general formulation for the problem of radiating fins with flat surfaces.
