STREMR: Numerical model for depthaveraged incompressible flow
Abstract
The STREMR computer code is a twodimensional model for depthaveraged incompressible flow. It accommodates irregular boundaries and nonuniform bathymetry, and it includes empirical corrections for turbulence and secondary flow. Although STREMR uses a rigidlid surface approximation, the resulting pressure is equivalent to the displacement of a free surface. Thus, the code can be used to model freesurface flow wherever the local Froude number is 0.5 or less. STREMR uses a finitevolume scheme to discretize and solve the governing equations for primary flow, secondary flow, and turbulence energy and dissipation rate. The turbulence equations are taken from the standard kEpsilon turbulence model, and the equation for secondary flow is developed herein. Appendices to this report summarize the principal equations, as well as the procedures used for their discrete solution.
