Abstract

In this paper, CFD simulation of evaporative cooling pad, which is one kind of structured packing, has been carried out in Liquid Desiccant Dehumidification System (LDDS). Dry pressure drop and liquid distribution of two types of evaporative cooling pad are simulated and validated by the experimental data and Nusselt formula. For conducting the simulation, micro-scale representative element of evaporative cooling pad is built. VOF model is adopted as multiple phase model. Three turbulence models are compared. By means of CFD simulation comparison, it is found that κ - ω is the most suitable turbulence model for the simulation of structured packing. The liquid distribution pattern inside the packing is uncovered. The influences of flute height of packing are obtained.
