Abstract
It is well-known that flow condition inside injection nozzles has much effect on spray characteristics. Despite its importance, the two-phase gas-liquid flow is difficult to be simulated by using computational fluid dynamics due to the existence of cavitation which involves small-scale and high-speed phase-change phenomena. To resolve this problem and to link between flow condition including the effect of cavitation and spray characteristics, the authors have developed a phenomenological modeling scheme. This paper proposes novel modeling schemes which make it possible to realize high-accuracy computations of growth and shrinkage processes of cavitation bubbles.
