Abstract
The purpose of this study is to build up the visualization system using CCD camera at low cost in the high pressure vessel which can pressurize water up to 40MPa.
The specification of the vessel is 1.988 m height, 0.635 m diameter and 0.6m3volume.
A cheap CCD camera installed in a small container is fixed near a table-tennis ball and a cup of styrene foam in the vessel.
Our visualization system succeeded to observing and recording the scenes of breaking of the ball at around 1 MPa and shrinking process of the cup up to 27 MPa.
