### Mathematical Model of a Wave Cooler SpringerLink

These equations are solved by a method of finite differences with allowance for discontinuities. A mathematical model of gas flow in a branching manifold was developed. The model assumes that the sizes of the branches are commensurate with a step of the grid in the tube and that it is possible to average flow parameters throughout all the branches.

2019-3-26 To develop a mathematical model of a thermal system we use the concept of an energy balance. The energy balance equation simply states that at any given location, or node, in a system, the heat into that node is equal to the heat out of the node plus any heat that is stored (heat is stored as increased temperature in thermal capacitances).

A mathematical model of the cooler was developed. Thermal balance tests, simulating the conditions of deep space vacuum and temperature and various orbit heat loads, were conducted to verify the model. The experience gained from the tests evolved ideas to improve the cooler performance which when implemented in practice really produced results.
