Optimization of the Mass and Hydraulic Characteristics of Radiators

Presented are the technique, mathematical model and software for implementation of the optimal design of the radiators in terms of the criterion of the minimum total mass with the added mass of the power board system accounted for. The mathematical model takes into account the losses of pressure required for pumping the heat-transfer fluid through the hydraulic system of the radiator. The optimum values of the geometric parameters of the radiator and heat-transfer fluid flow rate are determined. The generalized geometric programming algorithm is used for optimization.

Obtained are the results of solution as regards the radiators of the Orbital space station “MIR” research module. The recommendations covering reduction of the design mass of the radiators are disclosed. Both the technique the results can be used in design of other radiator systems of the space stations.
