Abstract A wave cooler with a dynamical system of cooling is considered in this work. A one-dimensional system of gas dynamic differential equations is used for describing the thermo-gas dynamic processes in the expansion tube and outlet manifold. 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. We have conducted the analysis of a device consisting of a stationary nozzle system with a moving aperture, which is arranged co-axially with the expansion tube.
