Efficient solution method for quasi two-dimensional model of water hammer

ABSTRACT

An existing solution method for the quasi two-dimensional model of transient flow in pipes has already been recognized as accurate, robust, and consistent with the physics. Its main disadvantage – numerical inefficiency, has recently been considerably reduced by introducing an improved solution procedure. This paper proposes a new and even more efficient solution procedure. The proposed method gives results that match the results of existing methods, but requires approximately 10% less central processing unit time than the improved procedure.
