Justification of the Method of Vehicle Engine Radiator Ultrasonic Cleaning

The article presents theoretical and experimental results on ultrasonic cleaning of a vehicle radiator. Criterion relationships between ultrasound energy, kinetic energy of the liquid, and shock wave energy were established, enabling the evaluation of cavitation energy efficiency and cleaning effectiveness. Experimental confirmation was obtained using a developed full-size bench. Using the developed full-size bench, the numerical values of parameters were obtained that made it possible to calculate the values of energies involved in the cavitation process, the ratio of which allows evaluating the effectiveness of washing the radiator from scale. The cavitation coefficient of erosion efficiency was established, proving the effectiveness of ultrasonic cleaning. Results confirm the applicability of this method for cleaning the vehicle radiators.
