Experimental study of the efficiency of heat and mass transfer during ultrasonic drying of textile materials

Abstract

The article presents the results of experimental studies of the process of ultrasonic drying of textile wool. It was found that additional ultrasonic exposure makes it possible to accelerate convective drying up to 7.5 times under constant initial experimental conditions. When cotton wool is exposed to ultrasound, thermal diffusion occurs. Water molecules move from the more heated center of the drying object to the less heated surface.
