Ultrasonic radiators for the action on gaseous media at high temperatures

摘要

The article is devoted to the study of influence of high temperature on the operation of the ultrasonic disk radiator intended for generation of high-intensity vibrations in gaseous media. As a result of researches it was determined, that temperature increase of gas and the radiator led to the rise of vibration amplitude of the surface of the disk radiator and the fall of level of acoustic pressure owing to the reduction of gas density.
