摘要/Abstract

摘要： 本文用Simpler算法结合人工压缩性方法并首创"分区解法"对我国现有三室一厅住宅模式的自然通风质量进行了数值模拟,获得了住宅内部的流场分布与压力分布等主要数据。相应形成的软件具有通用性,从而为优化居住建筑的通风质量提供有效的科学评判和分析手段。

Abstract: A numerical approach is presented for simulating the quality of natural ventilation in an apartment unit with three bedrooms and one hall by using algorithm of Simpler and Artificial compressing method based on blocked interior spaces,which obtained the main data on the distribution of laminar-flow field in a housing unit. The application software created accordingly applies universally,which provides an effective means for an alyzing,optimizing and evaluating the quality of natural ventilation in housing design.

Key words: Housing unit, Natural ventilation, two-dimensional laminar-flow, Algorithm of Simpler, distribution of laminar-flow field
