ABSTRACT:
A method for continuously monitoring and/or controlling the cooling capacity of a liquid coolant containing gas bubbles. The method comprising the steps of: (a) measuring the size and number density of the gas bubbles it he liquid coolant by use of a sensor means to infer a heat transfer characteristic of the liquid coolant; and (b) varying the amount of gas that is being mixed with the liquid coolant so that the inferred heat transfer characteristic is within a predetermined range.
