Abstract

The article continues the study of the gas-dynamic processes in internal channels, using the polarization interferometer with birefringent Wollaston prisms. For the first time, we have received the visualization patterns of the flow in the channels of the flat transparent model of the devices with multiple expansion of flow in pulsed mode and we have held the frame-by-frame digital processing. The features of the flow in an input cavity were detected and the trajectory of emission of the diaphragm parts was visualized. We have improved the structure of the attachment point of the blow-out diaphragm of impact unit to regulate the intensity of the pulse. The structure of the blow-out diaphragm, which does not damage the optical glass, was suggested. The visualization methods helped to expand the experimental opportunities of study of flows in complex internal channels. The results of the study can be used in experimental studies of items flow by gas under different conditions.
