| 摘 要： | 通风空调系统中送风口出流特性是影响室内气流组织的重要因素．在用数值模拟方法预测室内气流组织时，通常将送风口处的气流速度分布简化为均匀分布，而实际的通风空调系统，送风口前常接有弯头、三通、变径等部件，送风口出流可能存在不均匀、通过对送风管段内三维流动的数值模拟，分析送风口处的气流分布情况．数值模拟结果表明各送风口处流速分布存在不同程度的不均匀现象，如果进行室内气流组织的数值计算时，仍按均匀分布进口边界条件给定，则将会产生较大的误差。

| Abstract: | Flow patterns of supply-air outlets play an important role in deciding indoor air-flow organization.Air velocity distribution of supply air outlet is generally regarded as uniform distribution when indoor air-flow organization is tested.However,uneven distribution may be found in an actual system of ventilation and air conditioning due to such parts as elbows,tee bends and reducers in the front of outlets.The results of the numerical simulation indicated that errors tend to be found when numerical calculati... |
