摘要：

The objective of this study is a systematic experimental analysis of a cooling process of a hot stagnant stainless steel plate of 1ft(*)1.5ft and 20mm thickness by impinging circular water jets. The effect of the water temperature and the flow rate were analysed. The temperature history of the plate during the cooling process was measured with thermocouples within the plate and this data is gathered for numerical analysis. The different parameters that were considered during analysis are Nozzle to plate distance, nozzle gaps, different flow rates, and nozzle diameter during impingement of water jets on hot steel rolled plates. The effect of spray height on cooling was minor within the experimental conditions. The water temperature has negligible effect on the heat extraction within the experimental conditions of this study. The stationary plate has a significant effect on the heat fluxes and also the amount of energy extracted from the plate. (C) 2017 Published by Elsevier Ltd.
