概要
This work addresses LDI (Liquid Droplet Impingement) accompanied with pipe wall thinning in nuclear and thermal power plant s. In order to clarify the factors that affect the wall thinning, the structure of supersonic two-phase flow after an orifi ce is visualized with a digital video camera. The visualization experiment proves that the droplets impinges the pipe wall shortly after the orifice and that the amount of water droplets that passes through the orifice is the important parameter.
