对垂直向下进入房间的轴对称浮力空气射流进行了数值预测。用代数应力模型封闭平均输运方程，然后用有限体积法求解。数值方法追踪了射流的初始发展。负浮力导致逆流；由此产生的流动模式类似于一个倒置的喷泉。与喷泉相关的再循环对喷流实现的热混合水平具有重要影响。关键词:计算，湍流，浮力，空气射流，垂直，房间，再循环，空气运动，气流，热流，暖空气加热引文:研讨会，ASHRAE Trans。1994年，卷。 100，第二部分

A numerical prediction is presented for an axisymmetric buoyant air jet discharge vertically downward into a room. An algebraic stress model was used to close the mean transport equations which were then solved using the finite-volume method. The numerical method tracked the initial development of the jet. The negative buoyancy leads to flow reversal; the resultant flow pattern resembles an inverted fountain. The recirculation associated with the fountain has significant implications for the level of thermal mixing achieved by the jet.KEYWORDS: calculating, turbulent flow, buoyancy, air jets, vertical, rooms, recirculating, air movement, air flow, heat flow, warm air heating
