中文摘要：

＂烟囱会飞＂是指轻纸卷成圆筒被点燃上端之后能起飞的现象.根据空气热动力学原理和预实验,首先确定了纸筒上升的动力学参数,再通过引入牛顿内摩擦定律和流体流动特性参数的微分关系式建立了物理模型,在此基础上进行实验定量研究了＂迎面阻力＂这个主要的动力学参数,发展了一种计算其大小的新方法,并且讨论了它对纸筒上升的影响.实验简单易行,不仅能够作为设计性实验用于大学物理实验教学,而且可以由此解释生活中常见的热力学现象.

英文摘要：

Abstarct： ＂Flying chimney＂ means that a light paper tube can take off when it is lit at the up part. The kinetic parameters are firstly determined according to the air thermodynamic principles and the preliminary experiment. Meanwhile, a theoretical model is established based on Newton＇ s law of internal friction and the differential equation of fluid flow characteristic parameters. Furthermore, the main dynamic parameter ＂frontal resistance＂ is quantitatively investigated by the experiment and its effect on the tube rising is discussed. In addition, a new method is developed for calculating ＂frontal resistance＂. The experiment of ＂flying chimney＂ is simple, which can not only be used as a design experiment on college physics teaching but also can thus explain the thermodynamic phenomena in daily life. Key words ： ＂flying chimney＂ ; frontal resistance ; paper tube ; dynamic parameter
