Paper Abstract

Experimental considerations for control of the oscillation noise were performed for results of various steam vapor injecting visualization as in previous reports. These phenomena were observed by means of shadowgraphy using a high speed video camera and a still camera. These injecting patterns of the steam bubble were analyzed through the photographs selected from each picture film. Peak frequency and amount of the oscillation noise caused by the condensing vapor were dependent on subcooling and amount of the mixing ratio for injecting gas. These experiments were performed for atmospheric pressure, and for temperature differences between the saturated steam and water for subcooling 20-70. The present investigation was clarified that the condensing oscillation noise would have significant relationships for a quantity of thermal layer near the orifice surface. Temperature distribution on the orifice and S.P.L. of the condensing noise predicted for some visualized results had so much correlations. The effect of bulk temperature in a water tank and difference among a single orifice and the other orifice were discussed and good predictive results for the flow visualization in subcooled water.
