摘要

在室内环境中，影响气流特性和热舒适的因素很多。因此，为了调查这些因素的影响，进行了大量的研究。本研究的目的是确定在保持相同送风风量的情况下，供风面积对热人体占据的通风箱原型的气流特性和室内热舒适的影响。了解由热人体模型占据的机械通风箱中的气流行为是本文的主要目的。因此，采用ANSYS FLUENT 17.0软件进行数值模拟。所得结果表明，进口速度对速度场、温度、静压和湍流特性有直接影响。另外，数值结果也肯定了供气面积对室内热舒适有直接影响。

Computational study and experimental validation on the effect of inlet hole surface on airflow characteristics and thermal comfort in a box occupied by a thermal manikin

Abstract In an indoor environment, many factors may affect the airflow characteristics and thermal comfort. Hence, a lot of research has been carried out in order to investigate the impact of these factors. The purpose of this study is to determine the effect of supply area, with maintaining the same supply airflow rate, on the airflow characteristics and the indoor thermal comfort for a ventilated box prototype occupied by a thermal manikin. Understanding the behavior of the airflow in a mechanical ventilated box occupied by a thermal manikin is the main objective of this paper. Hence, numerical simulations were carried out using the software ANSYS FLUENT 17.0. According to the obtained results, the inlet velocity has a direct effect on the velocity fields, the temperature, the static pressure and the turbulence characteristics. In addition, the numerical results affirmed that the supply area has a direct impact on indoor thermal comfort.
