✦ Synopsis

Optimization of convective-radiative spines with an arbitrary profile is discussed.

The profile is assumed to be correlated to the temperature distribution in the spine. Various profiles are considered by introducing a free parameter. With this choice of profile, the nonlinear heat transfer equation is integrated analytically. The optimization problem is written in terms of an integrul that can be evaluated numerically. The temperature at the tip of the spine becomes an important optimization parameter in this analysis. The method is well suited ,for parametric studies and design analysis of optimum spines including temperature dependence of thermophysicalproperties.
