Modeling and analysis of the efficiency of the convective drying of capillary-porous bodies with ultrasound

摘要

Introduction of new process drying methods and development of new raw materials and additives is usually accompanied by a number of tests that are rather expensive and do not always guarantee an optimal result. A reliable and accurate prediction of the kinetic behavior of the unit heat-moisture condition by means of replacement of full-scale tests with a computational experiment should form the basis for effective drying process optimization. The conducted research has proved efficiency of mathematical modeling the heat moist condition of the capillary-porous body during convective drying with ultrasound. It has been established that ultrasound exposition during convective drying reduces its duration by 30...40 %. The research results may be used at developing new energy-effective drying technologies and improving existing ones.
