摘要
如何高效学习?如何培养学生的学习兴趣?这些都是当前各高校教学改革过程中面临的巨大难题。为了满足燃烧学、流体力学与数值模拟等实验教学的需要,按照弗洛德相似准则,设计搭建了1∶10缩尺寸多功能隧道火灾实验平台。该实验平台能够模拟隧道中小汽车着火的过程,有助于教师直观地解释燃烧学课程中火灾动力学的抽象原理,说明流体力学课程中相似性原理的应用,并在数值模拟课程教学中为数值模拟结果提供实验验证数据,进而说明模拟和实验的可靠性。该实验平台还可通过调节隧道坡度,研究隧道坡度对烟气流动的影响,为隧道安全研究提供重要的理论基础和数据支撑。
How to learn effectively?How to cultivate students'interest?These are huge problems in the teaching reform of various colleges and universities.To meet the needs of combustion science,fluid mechanics,numerical simulation and other teaching experiments,according to Froude similarity criterion,a l:10 small-scale multi-functional tunnel fire experimental platform was designed and built.The experimental platform can simulate the fire of a small car in the tunnel.In the teaching of combustion course,it can intuitively explain the abstract principles of fire dynamics;in the teaching of fluid mechanics course,the application of the principle of similarity can be explained with the help of experimental tables;in the teaching of numerical simulation course,the construction of the experimental platform can provide experimental verification data for the simulation results and illustrate the reliability of simulations and experiments.With the experimental platform,we can also study the influence of tunnel slope on flue gas flow by adjusting the tunnel slope,and then provide an important theoretical basis and data support for tunnel safety research.
