“…In addition, most researchers focused on the single jet impingement cooling. Robidou et al 5) and Karwa et al 6) studied the boiling heat transfer phenomenon and identified the boiling regimes by the snapshots observations and the boiling curves analysis. A high number of researchers investigated the rewetting phenomenon during water jet impingement, 7,8) characterizing the critical transfer from the film boiling regime to the nucleate boiling regime.…”

The design of cooling systems for running hot steel plates has received much attention because the mechanical and/or metallurgical properties of final products are greatly influenced by the cooling capacity of the system. Thus many steel makers have largely concentrated on simply increasing the cooling water supply capacity of the system. Some researchers believe that plate cooling is a type of thermal communication between the hot plate and the cooling water or the atmosphere, so they have emphasized the importance of thermal conditions such as the cooling water temperature or air humidity. Actually the cooling process is governed by the basic physics of boiling heat transfer between the hot steel plate and the cooling water. Therefore steel makers should be more concerned about the influence of the design parameters of cooling facilities on the boiling phenomenon rather than the simple increase of the cooling water flow rate. In this study, when the diameter of the nozzle supplying cooling water is changed, its effect on boiling heat transfer has been investigated numerically. The average heat flux, the Leidenfroststeam-layer thickness, the temperature drop and so on were investigated according to nozzle diameter.

“…The description of physical aspects of heat transfer related to similar problem of water jet cooling under steady state conditions has been given by Robidou et al [39]. The transition from nucleate boiling to film boiling under variable water velocity and distance from the nozzle to plate surface has been discussed.…”

A cooling rate affects the mechanical properties of steel which strongly depend on microstructure evolution processes. The heat transfer boundary condition for the numerical simulation of steel cooling by water jets can be determined from the local one dimensional or from the three dimensional inverse solutions in space and time. In the present study the inconel plate has been heated to about 900°C and then cooled by six circular water jets. The plate temperature has been measured by 30 thermocouples. The heat transfer coefficient and the heat flux distributions at the plate surface have been determined in time and space. The one dimensional solutions have given a local error to the heat transfer coefficient of about 35%. The three dimensional inverse solution has allowed reducing the local error to about 20%. The uncertainty test has confirmed that a better approximation of the heat transfer coefficient distribution over the cooled surface can be obtained even for limited number of thermocouples. In such a case it was necessary to constrain the inverse solution with the interpolated temperature sensors.
