気泡核生成モデルを考慮したノズル内キャビテーション現象に関する数値計算

抄録

It is known that the number of cavitation bubble nuclei increases exponentially as the degree of superheat of liquid increases. Bubble Nucleation Model is incorporated with general-purpose thermal fluid analysis software STAR-CCM+ which set constant number of bubble nuclei. The influence of the change in the number of bubble nucleus on the bubble collapse energy is verified.
