Finite Element Simulation of the Shear Effect of Ultrasonic on Heat Exchanger Descaling

摘要：

　　The shear effect on the interface of metal plate and its attached scale is an important mechanism of ultrasonic descaling,which is caused by the different propagation speed of ultrasonic wave in two different mediums.The propagating of ultrasonic wave on the shell is simulated based on the ANSYS/LS-DYNA explicit dynamic analysis.The distribution of shear stress in different paths under ultrasonic vibration is obtained through the finite element analysis and it reveals the main descaling mechanism of shear effect.The simulation result is helpful and enlightening to the reasonable design and the application of the ultrasonic scaling technology on heat exchanger.
