CAVITATION DURING THE MOVEMENT OF A HIGH-SPEED TRAIN

Abstract

The article deals with the processes that occur in the tail section of a high-speed train during normal movement at a speed of over 330 km/h. The conditions for the transformation of an air mass into a compressible liquid are analyzed. The influence of covitation and corrosion processes on the integrity of the train body has been studied.I.
