Impinging jets are known as a method of achieving particularly high heat transfer coefficients and are therefore employed in many engineering applications. This includes the cooling of turbine blades, workpiece cooling in grinding and the thermal management of electronics. The addition of a fine water mist to an air jet flow has the potential to achieve superior heat transfer coefficients in excess of conventional single-phase gas jet cooling. It is believed that the overall heat transfer can be enhanced even further with a better understanding of the fluid flow and heat transfer characteristics involved.
