Study of the thermal performance of water-soaked porous wall under a tropical climate

Abstract

The effects of water-soaked porous wall on the reduction of air temperature and cooled air distribution in adjacent rooms are not yet understood. This paper examines the thermal performance of water-soaked porous wall based on field experiments and analysis of humidified cooled air in adjacent spaces by using a computational fluid dynamic model. The results indicated that two rows of porous pipes are capable of reducing ambient air temperature by 2.2°C with a cooling capacity of 372.5-1792.7 W/m2. The simulation results at a wind velocity of 0.70 m/s showed that cooled air is distributed in the room up to 3.2 m away from the porous wall and mostly accumulated on the room's floor.
