ANALYSIS OF GAS COOLER FOR ASSORTED DESIGN PARAMETERS

Pray cooling is the most economical and simplest method of exhaust hot gas cooling. Water spray coolers are extensively used in all industries where hot exhaust cooling is mandatory. The spray coolers also play a crucial role in space research and defense research organizations during ground simulation testing to cool the exhaust gas. In spray cooler chamber, the hot gas is cooled by injecting the high pressure water as fine droplets through the orifices circumferentially arranged in different injection pl anes. The performance of the spray cooler is a function of different variables like mass flow rate of water, number of orifices, orifice diameter, droplet size, length of the spray cooler etc. A spray cooler is to be designed in such a way that it should d eliver best performance at lowest cost. In this research paper, a detailed CFD analysis has been carried out on the spray cooler and optimized the design parameters.
