title = "RELAP5 water-hammer benchmarking via a theta-implicit finite-element algorithm",
abstract = "Water hammer phenomena characterize pressure surges that can lead to pipe failure or liquid flashing. RELAP5 is a best-estimate two-phase thermal hydraulic engineering tool which solves a ID 6-equation model. RELAP5 was developed to analyze transients in nuclear power plants and the modeling of water hammer phenomena remains a benchmarking opportunity. A third-order accurate finite-element solution to the ID mass and momentum conservation principles is presented, specifically single-phase flow with wall friction. As an inviscid benchmarking example, a velocity profile is established between two constant pressure boundaries connected by a pipe segment. An instantaneous valve closure is initiated at to and the pressure and velocity profiles along the pipe segment are compared for the finite-element and RELAP5 simulations.",
