Nonconservative Formulation of Unsteady Pipe Flow
A new approach to numerical modeling of waterhammer is proposed. An unsteady pipe flow model is used, but, in contrast to the standard treatment of the unsteady friction term as a source term, the authors propose a nonconservative formulation of source term. Second order flux limited and high order numerical schemes were applied to the proposed formulation, and results are in better agreement with measurements when compared with results obtained with standard form.
