Abstract
Assessment of the performance of a shallow water model with closure using a linear k-ε turbulence
model is made for various obstruction-induced discontinuous flows. The monotone upwind scheme of
conservative laws (MUSCL) - Hancock scheme is used, together with the Harten Lax van Leer (HLL)
approximate Riemann solver in the discretization of the finite volume shallow water model. These kinds
of models contribute to the improvement of optimized design of various processes in chemical
engineering and technology. Two obstructed flow applications are presented, namely, single obstruction
and multiple obstruction induced discontinuous flows; and the ability of the shallow water model with the
k-ε based turbulence model to predict these applications are assessed. The simulation results of the
shallow water model are compared with those found by direct numerical simulation (DNS) and
experimental measurements in the literature
