摘要:

为了研究如何通过选择合理的布局方式来改善建筑群内的风环境,设计并进行了一系列的风洞试验,对整个建筑群的流场进行了测试以获得整体的风环境状况.通过研究风速比和布局参数、风向角的关系给出了便于设计应用的风速比等值线图.引入了行列式建筑群的无量纲布局参数的定义,以便于研究成果的应用;提出了最小化最大风速比和最小化非期望区域面积的两种优化设计理念,并应用这两种优化理念确定了小区的合理布局参数, 改善了风环境.

Abstract:

For  of arranging the buildings reasonably to improve the wind environment around buildings, a series of wind tunnel tests on the flow fields were designed and conducted so as to access to the overall status of the wind environment.  By studying the relationships between wind-velocity-ratios, layout parameters and wind direction angles, wind-velocity-ratio contours which are easy to be applied in actual cases were obtained. Non-dimensional layout parameters of residential quarters with parallel layout were designated in order to facilitate the application of the research findings. Two optimization design ideas, named as minimizing maximum wind ratio and minimizing non-expected region respectively, were proposed, according to which, the corresponding reasonable layout parameters were determined and  the wind environment was consequently improved.
