Study on the indoor airflow pattern and thermal comfort under cross ventilated situation of residential building by using domain decomposition technique

我们主要做了四种工作。关于交叉通风性能中预测的研究2。对各种开启条件的交叉通风性能的评估3。预测冷却传感器的方法是由交叉通风驱动的气流的预测方法。对舒适性传热的协同效应和热耐受性的研究表明，交叉通风下的服装主要结果如下。根据双排模拟结果对低边界条件的修改显示了一些影响，以改善交叉通风的室内气流结构的再生产准确性。结果显示，一般来说，风的速度比值C可以唯一地确定每个打开情况的位置或时间点，并确认评估交叉速度比C和ignores位置的方法的有效性。从交叉通风气流对使用者的冷却效应的结果来看，我们也发现了这样的结果，即使用数字热锰来实现相对较高的准确性预测是有可能的。在穿着高透气性的情况下，服装退化的热抵抗力为10- 20%，风速为0.5米/秒，风速为1米/秒，30- 40%。

We mainly did four kinds of studies.1. Study on prediction in cross-ventilation performance2. Evaluation of cross-ventilation performance of various opening conditions3. Prediction method of cooling sensation due to breezing airflow driven by cross-ventilation4. Study on the convective heat transfer coefficient and thermal resistance of clothing under cross ventilationThese main results are shown below.・Modification of inflow boundary conditions based on coupled simulation results showed some effect to improve reproduction accuracy of cross-ventilated indoor airflow structures.・The results showed that, generally speaking, the wind velocity ratio value C can be determined uniquely for each opening case, almost regardless of the location or time slot, and confirmed the validity of the method of evaluating cross-ventilation performance which uses the wind velocity ratio C and ignores locality.・From the results of the cooling effect of cross-ventilation airflow had on the occupants, we also found that it is possible to perform relatively high-accuracy prediction by using numerical thermal mannequin with decoupled CFD technique.・ In the case of clothing with high breathability, thermal resistance of clothing decreased by 10-20% at a wind speed of 0.5 m/s, 20% at a wind speed of 1 m/s, and 30-40% at a wind speed of 2 m/s.
