Abstract

Computational fluid dynamics analysis of a building plan has been investigated with predominant wind velocity for different wind directions. The flow properties’ variation in the computational domain has been modeled by solving the Reynolds-Averaged Navier–Stokes (RANS) equations with the finite volume second-order discretization scheme. The turbulence of airflow distribution in and around the building has been modeled with the Shear Stress Transport (SST) k–ω turbulence model from the analysis of different turbulence models. Numerical results are analysed by evaluating and comparing the various flow properties at different building plan locations with different wind directions. The development of pressure coefficients, wind-driven driving force, and air change per hour are studied for different wind directions. From the analysis of numerical results, it is identified that better ventilation with sufficient airflow distribution has existed when the wind is coming from the west direction.

针对不同风向的常规建筑计划的气流分布的CFD分析

摘要

已经针对不同风向的主要风速研究了建筑计划的计算流体动力学分析。通过使用有限体积二阶离散化方案求解雷诺平均Navier-Stokes（RANS）方程，可以对计算域中的流动特性变化进行建模。建筑物内及其周围的气流分布湍流已通过剪切应力传递（SST）k进行了建模–ω湍流模型来自对不同湍流模型的分析。通过评估和比较具有不同风向的不同建筑计划位置的各种流动特性来分析数值结果。研究了不同风向下压力系数，风力驱动力和每小时换气量的变化。通过对数值结果的分析，可以确定，当风来自西风方向时，存在通风良好且气流分布充分的通风方式。
