Abstract : A theoretical analysis of ultrasonic cavitation was made and experiments were conducted on acoustical measurements under cavitation conditions. An equation for the critical radius of a gas nucleus forming in liquids under metastable thermodynamic conditions was obtained. An equation is also given for the total volume of gas nuclei formed during cavitation at a frequency of 20 Kc in the temperature range 10-60C, for different molal air contents dissolved in water. Experimental results showed that cavitation was highly dependent on the gas content of the liquid. (Author)
