The cavitation chamber creates cumulative micro-jets generated at collapse of cavitation bubbles. The shape of any cross section of any cavitation chamber can coincide or not coincide with the shape of cross section of the tube proper; the area of its flow channel can be equal or exceed corresponding area of cross section of the tube proper; an external contour of any such cross section and the contour of the flow channel can be of any shape.
