High-pressure injection systems have been installed for the purpose of reducing toxic exhaust gas from diesel engines in recent years. However, the cavitation phenomenon and erosion occur in the high-pressure pipe system due to the large pressure fluctuations at the end of fuel injection. Therefore, there is strong demand for clarification of the cavitation phenomenon under a fluctuating pressure field. For this reason, behavior of cavitation bubbles in liquid fuel under a fluctuating pressure field in a pipeline was investigated in the experiments presented here.
