Caractérisation du refroidissement par jet liquide impactant une plaque métallique à haute température : Iinfluence de la composition du fluide sur le flux extrait

Abstract : In this work, we are interested in the influence of the fluid's composition on the cooling flux. In fact water used for cooling is recycled and can be potentially polluted by residues oil from the lubrication of rolling cylinder. We have designed an original experimental device which consists of heating a Nickel disk on its upper face at temperatures of 600°C through electromagnetic induction and then cooling it by jet impingement. The reverse face is available by infrared thermography measurements. These conditions allowed us to estimate the heat flux on the upper face (the cooling area) by infrared thermography measurements with a specific inverse heat conduction model. The results showed that the presence of oil, if it degrades the maximum cooling flux in some areas, led to a better overall cooling than that obtained with pure water.
