Boiling Heat Transfer for a Plane Water Jet Impinging on a Hot Surface

Heat transfer behavior in the impingement zone under circular water jet

“…For the film boiling in water pool cooling, the heat flux decreases with the decrease of surface temperature to a minimum heat flux value. This feature was also reported in reference [16] for water jet cooling. In the case shown in Fig.…”

“…Numerous researches, both experimental and/or numerical, have been performed on the subject of water jet cooling [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. This prior research work has constituted insight into the water jet cooling on ROT but there are still to some extent many important points to be examined.…”

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

“…6, the cooling medium has high vertical velocity, the boiling bubble is washed out quickly, the boundary layer is very thin in this zone, and temperature difference is large, therefore, the high heat flux density appears in this zone. This has a good agreement with the results founded by Ishigai [29] and Hall [30], etc. The heat transfer temperature difference decreases quickly due to the high heat transfer efficiency on P3 measuring point, the duration of critical heat flux density is short for the zone I.…”

Jet impingement quenching phenomena for hot surfaces well above the limiting temperature for solid–liquid contact

“…The reason why the value of q max is lower than the Monde et al prediction is mainly because of the heat transfer limitation caused by thermal properties of the block quenched as mentioned by Mozumder et al [14]. The minimum film boiling heat flux (q MFB ) for the experimental conditions is about 0.43 MW/m 2 whereas it is about 1.66 MW/m 2 as predicted by Ishigai et al [15]. It is worth mentioning that the prediction of Ishigai et al [15] is a correlation developed for jet velocity less than 5 m/s.…”

“…Ishigai et al [15] observed no solid-liquid contact in the film boiling region. The beginning of the contact is often understood to coincide with the minimum heat flux point.…”
