从简化均匀圆管脉动流动的Navier—stokes运动方程出发,避开了Bessel函数的复杂推导和繁琐的函数表格,得到比Womersley脉动流方程更为直接和简单的解析形式,为用脉搏波进行血流计算提供一个简便而实用的分析方法。
Starting from the simplified Navier-Stokes equations of motion of uniform circular tube flow, the complicated derivation of the Bessel function and the tedious function table are avoided. A more direct and simple analytical form than the Womersley pulsation flow equation is obtained. Flow calculation provides a simple and practical method of analysis.
