Quenching of Flat Glass by Impinging Air Jets

Impingement pressure characteristics of swirling and non-swirling turbulent jets

“…7) there is no data to support the occurrence of vortex breakdown. Data acquired at Re = 24,600 (cases I24S000-I24085) and Re = 11,600 (cases I11S000-I11S074) 1 shows fundamentally the same behaviour observed at Re = 35,000. However, as the Reynolds number decreases to Re = 24,600 and then 11,600, the abrupt change in trends for velocity profiles occur at the lower swirl number of S = 0.58 and then S = 0.32, respectively.…”

“…Impinging jets are widespread in industrial applications due to their ability to affect heat and mass transfer rates on surfaces [1][2][3][4]. In a typical impingement jet, the flow field is divided into three regions, namely the free jet region, the stagnation (or impingement) region and the wall jet region.…”

The effect of inflow conditions on the development of non-swirling versus swirling impinging turbulent jets

“…Impinging jets have received significant attention due to their inherent complex nature and ability to affect convective heat transfer in a variety of applications, ranging from glass tempering [1][2][3] to turbine blade cooling [4,5], drying or freezing [6,7] as well as flame-plate interactions [8][9][10]. Several reviews of turbulent (axisymmetric) non-swirling impinging jets are available in the literature [11][12][13][14][15].…”

Numerical Simulation of Optimal Multiple-Input, Multiple-Output Control of Jet Impingement Cooling of a Glass Plate

“…It has been reported that an array of oscillating nozzles produces a relatively uniform rate of heat transfer and hence more uniform cooling [1]. In all these works the temperature history of either a stationary or moving substrate is obtained for a constant mass flow rate of the coolant.…”

“…Extensive work has been done on cooling of stationary as well as moving plates [1][2][3][4][5][6] by jet impingement. It has been reported that an array of oscillating nozzles produces a relatively uniform rate of heat transfer and hence more uniform cooling [1].…”
