Wavelets in the investigation of the cavitation processes in pump

In the article the main principles of lowering of a noise of an exhaust of pneumatic systems surveyed. The expediency of lowering of exhaust speed of an exhaust jet, and also splitting it on set many direction jets, by means of application of a silencer is justified. The mathematical model of calculation of a noise level created exhaust jet designed in view of the installation of a silencer also permitting to calculate transients in the pneumatic system. The outcomes of simulation of transients, and also calculation of efficiency of a silencer are shown. Matching calculation datas of pressure drop in pneumocapacity with experimental is carried out.
