HEAT TRANSFER AUGMENTATION IN STEEL QUENCHING BY SPRAY IMPINGEMENT COOLING ME...BIBHUTI BHUSAN SAMANTARAY
The present article discusses the experimental results on heat transfer characteristics of spray impingement cooling of a stationary steel plate. The eexperimental setup consisted of an electrically heated flat stationary steel plate of dimension 120 mm x 120 mm x 4 mm, spray setup, water supply and air supply unit. The effects of various controlling parameters such as air-water pressures, water flow rate, nozzle tip to target distance and impingement density were determined and analysed. The cooling rates were computed from the time dependent temperature history and used to analyse the parametric effects. The results obtained in the study confirmed the higher efficiency of the spray cooling system and the cooling strategy was found advantageous over the conventional cooling methods available in the open literature.
