A series of experiments in a wind tunnel using optoelectronic instruments has been carried out. Flow in a 2D ultrasonic nozzle was investigated. Experimental results were obtained using three methods – the shadow method, the schlieren method and holographic interferometry, which are compared with the classical method of measuring pressure and the results of numerical calculations.
