Finite Volume Method for Computation of Water Hammer in Conical Tubes

Abstract:

The most traditional way to calculate water hammer in the conical tube is using some small discrete equivalent uniform tubes to replace it. this approximate treatment can not show the much accurate results of the conical tube,but also not reflect the actual physical discontinuities of the system.This paper use finite volume method to integrate water hammer equations in conical tubes on spatial and temporal scales.Compare the results of FVM discrete equations with MOC. Conclusion shows that: the new discrete equations not only has high accuracy and stability in the calculation of water hammer in conical tubes,but also has a simple derivation process and clear physical meanings.This method provides a new way of thinking in water hammer calculation of conical tubes.
