【摘要】：通過實(shí)驗(yàn)研究不凝結(jié)氣體(空氣)對(duì)蒸汽浸沒射流壓力振蕩特性的影響。結(jié)果表明:不凝結(jié)氣體存在時(shí)壓力振蕩強(qiáng)度比純蒸汽浸沒射流時(shí)明顯減小。隨空氣質(zhì)量分?jǐn)?shù)的增加,壓力振蕩峰值的位置沿軸向后移。過冷水溫低于45℃時(shí),峰值隨空氣質(zhì)量分?jǐn)?shù)的增加而增大;高于50℃時(shí),隨空氣質(zhì)量分?jǐn)?shù)的增加而減小;水溫在45~50℃之間時(shí),峰值大致相同。壓力振蕩主頻隨空氣質(zhì)量分?jǐn)?shù)、蒸汽質(zhì)量流率和過冷水溫度的增加而減小。
[Abstract]:Experimental study of uncondensed gases (air). The results show that the pressure oscillation intensity in the absence of condensate gas is significantly lower than that in pure steam immersion jet, and the pressure oscillation intensity decreases with the increase of air mass fraction. The position of the peak value of the pressure oscillation moves backward along the axial direction. When the temperature of the supercooled water is lower than 45 鈩，
