本文介绍了一种结合气流、热辐射和水分输运的数值模拟方法来预测人体放热。还采用人体热生理模型来研究人体的感热和潜热传递。采用三维计算流体力学（CFD）方法研究了水流场、温度场和湿度场。我们采用低雷诺数型k-epsilon湍流模型，用广义曲线坐标系来表示人体的复杂形状。热辐射用Gebhart吸收因子法计算，视因子用蒙特卡罗法计算。我们采用Gagge的双节点模型模拟人体的代谢性产热和体温调节控制过程。预测结果与实际人体在类似情况下的结果非常接近。(C) 2000 Elsevier Science Ltd.版权所有。
This paper described a combined numerical simulation method of airflow, thermal radiation and moisture transport for predicting heat release from a human body. A human thermo-physiological model was also included to examine the sensible and latent heat transfer from the human body. Flow, temperature and moisture fields were investigated with three-dimensional Computational Fluid Dynamics (CFD). We used a low-Reynolds-number type k-epsilon turbulence model, with the generalized curvilinear coordinate system to represent the complicated shape of the human body. The thermal radiation was calculated by means of Gebhart's absorption factor method, and the view factors were obtained by the Monte Carlo method. We adopted Gagge's two-node model to simulate the metabolic heat production and the thermoregulatory control processes of the human body. The predicted results were very close to those of an actual human body in a similar situation. (C) 2000 Elsevier Science Ltd. All rights reserved.
