摘要
流动现象的分析、流体的动量守恒规律及其数学形式的奈维-斯托克斯方程的应用,在化工教学中有待强调。对于转子流量计的浮子升力及离心泵扬程产生的机理,《化工原理》教材中习惯以机械能守恒原理为依据进行阐释,相关内容有必要补充完善。
It is expected to emphasize the principles of momentum transfer in teaching process to help students understand flow phenomenon comprehensively. Two cases related with rotor meter and centrifu- gal pump is represented here, in which mechanical-energy balance are usually dependent to explain the operating principle, and convenient alternatives are described here by means of momentum balance and Navier-Stokes equations.
