新型流体力学动量定律实验仪的研制和应用

Development and Application of a New Fluid Mechanics Momentum Principle Instrument

动量定律实验是流体力学中的经典实验。针对传统实验仪器采用加重物法造成的低精度、无法精确测定射流的动量修正因数的问题。使用现代测试技术来进行改良,计改进后的实验仪器具有更高的精度,对流体力学实验教学改革产生重大影响。同时使学生的动手能力、思维能力和自主创新能力都得到了很大的提高。

The experiment of momentum law is a classical experiment in fluid mechanics. The problem of the low precision of the weight method and the momentum correction factor cannot be determined accurately. With the use of modern test techniques to improve,the improved experimental instrument has a higher precision,and the experimental teaching reform of convective physical education has a great impact. At the same time,students ＇ practical ability,thinking ability and independent innovation ability have been greatly improved.
