| 摘 要： | 在建立非等温射流运动的物理方程时,考虑由室内热源形成的羽状气流对射流运动的热浮升作用力,得到受羽状气流作用的射流运动轨迹表达式.经现场实测验证后,上述理论分析认为,空调射流与羽状气流的相互作用会影响射流轨迹,且在一定程度上改变其运行轨迹.

| Abstract: | The mathematical model was established to investigate the interaction between the plume and the non-isothermal jet.A new expression for considering the effect of heat sources on the non-isothermal jet was deduced.Experiments were carried out to validate the theoretic analysis,which agrees with the experiment data.The paper presents that the heat sources really have effect on the jet-track,which should be paid more attention to. |
