Jet flows impacting on a surface are referred to as Impinging Jets and widely recognized as an efficient method to achieve high heat and mass transfer rates. The addition of an azimuthal component to the stream introduces a swirling motion to a free flow generated by a round nozzle, enhancing turbulent mixing, heat and mass transfer, and flame stabilization, making the swirling jets widely applicable in many engineering fields. The rotational motion is typically achieved by passive methods such as guided vanes or rotating perforated plates. For some applications such as electronics cooling, high values of heat and mass transfer with radial uniformity are requested.
