ABSTRACT

A mathematical model of an emitting finned tube with an arbitrary number of rectangular fins and nonblack emitting surfaces is considered. Optimization of the structure has been done to obtain a maximum of the emitted heat flux and a minimum of the over-all mass of fins. It is shown that for the geometric parameters that satisfy the requirements of a maximum heat flux the requirement of a minimum mass is also met, as well as the optimal configuration of a rib at a fixed mass is preserved, which makes it possible to find the best parameters of the structure without resorting to optimization.
