ABSTRACT:
A gas-liquid cleaning spray system employs one or more converging-diverging nozzles to accelerate a gas-liquid mixture to a supersonic velocity for cleaning various types of articles, such as mechanical, electrical and fluid components. The gas, such as air or nitrogen, is supplied at high pressure to a nozzle body where it is mixed with cleaning liquid, such as water or liquid detergent, which is supplied to the nozzle body at a relatively low flow rate. Acceleration of the gas-liquid mixture to a supersonic velocity eliminates the need for a high pressure, high flow rate and high volume liquid supply. After the components are contacted with the gas-liquid mixture, the cleaning liquid can be recaptured and analyzed for cleanliness verification of the components.
