ABSTRACT

Heat transfer characteristics of shower cooling on a hot flat steel plate were investigated using the transient temperature measurement technique. Two shower cooling configurations adapted to cool the flat stationary steel surface of 4 mm thickness were directly compared for various factors such as initial plate temperature, water flow rates, average and local impingement density variation, and shower tip-to-plate space. The dimensionless initial temperature difference (ΔT*i) of the plate ranged from 6.67 to 16.67. The local and average impingement densities were measured by means of a simple mechanical patternator. A transient temperature measurement technique was applied with the help of K-type thermocouples embedded at the bottom surface of the plate. The observation revealed that optimum shower hole arrangement and design of the showerhead could achieve a higher cooling rate from a steel surface at higher temperature. For given water flow rates, local impingement density distribution decreases with increase in shower tip-to-plate distance. The mass flux profiles obtained for two different showers show quite different trends.
