Abstract |
Heat transfer studies of a hot AISI 304 stainless steel plate by water jet impingement with different concentrations of three different types of surfactants have been investigated. The study involves a square plate of 100?mm?×?100?mm surface area and 6?mm thickness with three subsurface thermocouples positioned at various locations inside the plate. The influence of jet height has been studied by varying the distance between the nozzle and plate from 200?mm to 600?mm. The results show that the heat transfer rate is found to increase with the jet height up to 400?mm and thereafter decreases due to capillary instability of liquid jet. Based on the maximum surface heat flux obtained for a particular nozzle height of 400?mm and an initial surface temperature of 900?°C, further experiments have been carried out with different types of surfactants....
