通过计算流体动力学 (CFD) 技术分析风对人体的热和动态影响。在各种风力条件下检查风对人体的影响。首先，人体处于停滞的风环境中。其次，将人体置于风速为0.25 m/s的微弱风中，并具有多个湍流强度值。接下来，攻击人体的风速增加到2.5m/s。最后，两具人体排成一排，迎着即将来临的风。详细计算人体周围的速度场和温度场以及体表的压力场。计算人体的阻力系数和对流传热系数。速度场和温度场的预测结果与先前的实验数据相当吻合。 (C) 1999 Elsevier Science Ltd. 保留所有权利。
The thermal and dynamic effects of wind on a human body are analyzed by means of computational fluid dynamics (CFD) technique. Wind effects on a human body are examined under various wind conditions. At first, the human body is placed in a stagnant wind environment. Secondly, the human body is set in a weak wind of velocity 0.25 m/s, with several values of turbulence intensity. Next, the wind velocity attacking the human body is increased to 2.5 m/s. Lastly, two human bodies are arranged standing in a row, facing the approaching wind. The velocity and temperature fields around the human body as well as the pressure field over the body surface are computed in detail. The drag coefficient and the convective heat transfer coefficient of the human body are calculated. The predicted results of velocity and temperature fields agree reasonably with previous experimental data. (C) 1999 Elsevier Science Ltd. All rights reserved.
