A New Method Based On The CFD And Multizone-model To Analysis The Natural Ventilation In Office Building

The analysis of natural ventilation has got a rapid development in theory andpractice promoted by the CFD technique .We can not only simulate the state of thenatural ventilation in the buildings, but also predict parameters about the thermalenvironments and the indoor air quality of the buildings.This paper gives a new method to analysis the natural ventilation based on theCFD technique. It aims to use the multi-zone method to analysis the buildingscomprised complex room. To give a scientific conclusion, it analysis the parametersof mean air age, thermal environments and mean speed of air with the numericalmathematics method. As a conclusion, it gives a serial of curves to show therelationship between the evaluation vote and the air speed. From the curves we canfind many useful suggestions to assistant natural ventilation design in buildings.This paper also quest for a method to analysis the natural ventilation in thebuildings comprised complex room. It just based on the CFD technique andmulti-zone model method.
