Energy-Based Evaluation of 1D Unsteady Friction Models for Classic Laminar Water Hammer with Comparison to CFD
Abstract
Under the umbrella of one-dimensional (1D) transient flow analysis, unsteady friction models are popular tools to better represent the decay in pressure signal associated with high wall shear stresses. There are generally two families of unsteady friction models, namely those based on instantaneous acceleration (IAB) and those based on convolution (CB). This paper considers a classic laminar water hammer and compares two unsteady friction …
