The influence of spray inclination angle on the ultra fast cooling of steel plate in spray cooling condition

Jet cooling for rolling bearings: Flow visualization and temperature distribution

“…Many industrial applications use impinging liquid jet to provide an effective mode of heat transfer, such as electrical motor [1], gearbox [2] and steel rolling [3]. For high-speed transmission systems, such as aircraft engines, turbomachinery, and drive trains, oil-jet is applied to the ball bearing cooling [4].…”

Investigation of a spray cooling system with two nozzles for space application

“…Parameters like droplet size [6,7], impact velocity [8], nozzle type [9], arrangement of multi-nozzle [10,11,12], subcooling degree [13,14], spray angle [9,15,16] and heated surface structure [11,17] have been proven significantly correlated with the system performance. Furthermore, the relevance of spray cooling in space technology and the unknowns related with the change in behaviour in microgravity have triggered intensive research into the influence of gravity.…”

Experimental research on spray characteristics and heat transfer of cast-rolled strip subjected to impinging air-atomized cooling

“…The model accounted for the expansion of the thermal boundary layers in the spreading drop and in the solid substrate, and for the evaporation of the liquid phase, leading to the creation of a thin vapour layer. Fu et al [15] and Panda et al [16] studied the ultra-fast cooling (UFC) widely used in hot rolled steel. Under spray cooling condition, Fu et al [15] experimentally investigated the UFC of the steel plate of 10 mm in the thickness direction and the spray inclination angle ranges from 0° to 60°.…”

“…Fu et al [15] and Panda et al [16] studied the ultra-fast cooling (UFC) widely used in hot rolled steel. Under spray cooling condition, Fu et al [15] experimentally investigated the UFC of the steel plate of 10 mm in the thickness direction and the spray inclination angle ranges from 0° to 60°. The transient heat flux density and temperature field in the plate surface were established with the inverse heat conduction method based on the measured temperature of the plate.…”
