Fundamental analysis of dew-point evaporative cooler

Research output: Chapter in Book/Report/Conference proceedingChapter


The performance of dew-point evaporative cooling is controlled by the fundamental physical processes related to fluid flow and heat and mass transfer. Investigation of these processes is crucial to reveal the underlying mechanisms and dominant factors of the cooler. This chapter presents several important methods that can be used to fundamentally analyze the dew-point evaporative cooling based on its CFD model developed in the last chapter. The scaling and dimensional analyses are basic yet powerful approaches for identifying the dominant dimensionless numbers of the cooling process and quantifying their influence on the objective parameters of the cooler. They can also be applied to examine the complex heat and mass transfer phenomena in the cooler that deviate from conventional constant boundaries. In addition, the exergy analysis is another approach to gain key insights into the irreversibility and potential of the dew-point evaporative cooling. It is worth noting that the methods presented in this chapter are feasible to any energy system, and a comprehensive understanding of the physical principles can be obtained by integrating these techniques.
