The wind flow around a building is a main point of the micro climate. We simulated the micro climate of a new housing area in C city with STAR-CD, STAR-Design. The prevating wind direction in C city was W and E. It was from Metcorological Administration date. Wind pressure of wind ward at the sample house was higher then ether areas. We got the wind pressure and wind velocity data from CFD simulations. Using these wind velocity data, we simulation indoor air flow in two-story detected house. The result was as follows; 1) The window pressure is changing according to the housing layout. Wind ward pressure was 1.8¡1.5Pa in C city Housing area. 2) Indoor air flow pattern in two-story detached house was simulated inlet of detached house was in west site and east side the pattern of two cases were shown. 3) The simulation of different outlet also studied. |
