Abstract
A method and apparatus for continuously monitoring the cooling capacity of a liquid coolant containing gas bubbles. The apparatus includes a measuring means for measuring the number density of the bubbles to infer the heat transfer characteristics of the liquid coolant, a control means for varying the amount of gas in the liquid coolant so that the number density is within a predetermined range and an electro-acoustic transducer in fluid contact with the liquid coolant capable of generating waves of sufficient intensity to cause cavitation in the liquid coolant in the area of the measuring means. In a preferred embodiment the electro-acoustic transducer is an ultrasonic horn.
