IMPULSE DETECTION METHOD TO INNER WALL OF CONTAINER AND ITS DETECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an impulse detection method to an inner wall of a container and its detection system capable of anticipating the damage to the inner wall of the container without changing the shape of the flow path and without damaging the measurement device by an optical remote measurement.;SOLUTION: The impulse detection method for the inner wall of the container is the method for detecting the impulse pressure caused by the cavitation to the inner wall of the container 2, wherein a stress luminescent particle is fixed on the inner wall of the container, at the time of impulse pressure is imparted to the inner wall of the container, the radiated light from the stress luminescent particle is received for detecting the impulse on the inner wall of the container. The reception of the light is performed under the condition that the liquid is flowing in the container 2 or the liquid is stored in the container 2.;COPYRIGHT: (C)2007,JPO&INPIT
