METHOD FOR VISUALIZATION OF GAS FLOWS AT SIMULATION OF PROCESSES IN DEVICES FOR REDUCING SHOT NOISE LEVEL

摘要

A method for visualization of gas flows at simulation of processes in devices for reducing level of shot noise relates to experimental gas dynamics and to the systems for testing small arms. The method includes introduction of dye in the flow that goes round the model, with fixation of the pattern of visualization. The dye is introduced in flow through affecting it with blast wave that is formed at pulse opening of a valve, or destruction of a diaphragm, on surfaces of which one places portion of dye before that. The method provides increase of reliability and quality of parameters being measured at modeling conditions of shot, this increases its efficiency.
