... magnitude is known as slippage velocity. Slippage velocity and flow regime in a pipe are affected by the density difference of each existing phase, liquid holdup, and inclination angle ( Bahrami, Hosseinian, & Rasouli, 2010 ). Basic Theory The application of Computational Fluid Dynamics, although...

.... The P-wave velocity calculated from the stiffness tensor is a used to connect the experimental data and field data. P-wave velocity is increasing as the bedding inclination angle increases. The predicted compressional wave velocity for a 45-degree inclination angle showed a perfect fit with the field...
