Abstract :This paper reveals some of the experimental results retained during the comprehensive experimental research on the direct contact dehumidification process in a washer dryer machine. Pressurized spray water is injected into the moist air subject to dehumidification; the interplay between the saturated water droplet and process air leads to direct contact condensation occurring on the droplet surface. As a result, latent heat of condensation is released, and saturated water temperature increases. This study investigates the detailed interaction between these two streams and evaluates the effects of temperature distribution with the elapsed time over the moisture removal rates. Results show that numerical results are generally in line with the experimental work, which proves the applicability of the Computational Fluid Dynamic (CFD) solutions to this tedious system modelling process.
