Abstract
Target vessel wall being damaged by pitting caused by pressure waves generated when pulsed high-power beams are injected is a crucial issue in the realization of a pulsed high-power mercury target for spallation neutron sources. The injection of micro-bubbles into mercury is a prospective technology for use in mitigating the pressure wave and the resulting pitting. The bubble flow field in an actual target vessel was numerically examined and the optimal conditions for bubble injection were investigated. The results indicated the possibility of the bubbles being distributed over the core regions when they are injected in the appropriate position according to their diameter.
