N2 - In order to obtain the pressure oscillation characteristics induced by steam jet in water, the experimental method was used to investigate the pressure oscillation in a wide range of steam mass fluxes and water temperatures. The pressure oscillation amplitudes at various positions were measured using high frequency pressure sensor, and the effects of steam mass flux and water temperature on the amplitude were analyzed combined with the flow patterns. The results indicated that the pressure oscillation was intense at condensation oscillation region, and was relaxative at stable steam jet region. The amplitudes decreased firstly then increased with the steam mass flux due to the transition of flow patterns. Moreover, the amplitudes increased with water temperature, and especially as the water temperature was higher than 40°C, the flow pattern became divergent which leaded to a significant increase in amplitude.
