在拉普拉斯空间中进行试井分析是一个有效的方法,我们可以将实测数据经过拉普拉斯变换到拉普拉斯空间中去,然后再在拉普拉斯空间中进行试井分析,这在本文中作了详细论述并且给出了实例。

The calculation of the rotordynamic coefficients of a multistepped annular seal in hydraulic turbines is discussed in this paper. Based on the Hirs' turbulence lubrication theory and the bulk flow model, the governing equations for the flow in the seal are developed by using the Moody's friction equations. The governing equations are perturbed when the rotor and the stator are coaxial. The Runge Kutta integration method and the Newton Raphson iteration method are used to solve the perturbation equations....
