Original Abstract

A special apparatus was developed in order to study cooling of the vertically moving hot steel surfaces by full cone nozzles. This apparatus allowed movement of the test sheet in the vertical direction up and down. Experiments with different water pressures and flow rate were conducted. It was observed, that the value of the average heat transfer coefficient is increasing with increasing water pressure within all the surface temperature range and that the dependence of the heat transfer coefficient on the water impingement density is linear in the region of stable film boiling. A mathematical model based on regression analysis for predicting heat transfer coefficient in the region of stable film boiling was developed.
