A study of the effectiveness of mechanical ventilation systems of a hawker center in Singapore using CFD simulations

Field measurements and thermal comfort survey were carried out to evaluate the thermal comfort perceptions of a Hong Kong hawker center. CFD simulations were conducted in order to study the impact of three kinds of fans on thermal comfort on the one hand, and to determine the type of fan (wall fan, ceiling fan or extract fan) which could improve best the thermal conditions in that hawker center.
