Experimental study of a cavitation heat generator

Abstract

Recent research has investigated the use of ultrasonic or hydrodynamic cavitation for chemical reactors, water treatment equipment, and heat generators. In this article, a new cavitation heat generator is introduced. The proposed system utilizes an electric motor to rotate the generator, and various experiments are performed by changing the flow conditions such as inlet pressure and rotating velocity to evaluate the performance of it. In addition, the amount of heat generation is measured and the thermal efficiency is evaluated. The result is a highly efficient heat generator that can reach 90% thermal efficiency.
