“…jet configuration and jet size, fluid flow rate or Reynolds number, surface and fluid temperature, fluid types, jet exit to surface spacing, surface orientation, and roughness etc . The commonly used fluids in jet impingement cooling are air and water, however, some research has also been reported with other fluids viz. fluorocarbons (FC), Freons, Nanofluids, and oil .…”

Heat transfer performance with jet impingement quenching of ferrous and non ferrous surface are reviewed for transient cooling condition. The surface rewetting performance during quenching is critically reviewed for various rewetting parameters viz. rewetting temperature, wetting delay, maximum surface heat flux, and rewetting velocity. These rewetting parameters are further assessed for the parameters pertaining to hot surface and coolant. Various published correlations for all the mode of boiling heat transfer and rewetting parameters are also encapsulated in the present review work.

“…In addition, at the measurement point 14 in the three jet cross-interference region, the surface temperature decreased slowly at first, whereas subsequently to 1 s it decreased faster. This phenomenon was ascribed to the water flow higher violent vortex, which could effectively carry away the bubbles attached onto the hot plate surface 15) and increase both the boiling frequency and the heat extraction quantity.…”

“…The cooling efficiency decreased along with the nozzle arrangement density, whereas the average heat flux did not increase monotonously along with the flow rate increase. Xie et al 15) studied the both the surface flow field and the heat transfer of a high temperature plate cooled by nine-nozzle arrays with various Reynolds numbers. The results demonstrated that the maximum heat flux, the corresponding surface temperature and time period at each measurement point were dependent on the distance from both the impinging point and the jet velocity.…”

“…[1][2][3][4] The UFC equipment impinges cooling water of 0.4-0.8 MPa onto plate surface of high-temperature through densely arranged nozzles to make steel quickly pass through austenite phase zone, and "freeze" hardened austenite to the dynamic transformation temperature of austenite to ferrite. [5][6][7][8] Increasing the cooling ability of UFC equipment can improve production efficiency and make the production of high-quality steel products possible. Lots of research had been done to improve the heat transfer performance of jet impingement.…”
