ZEPHYR3D: A finite difference computer program for three-dimensional, transient incompressible flow problems
This report describes the finite difference computer code ZEPHYR3D, which is designed to solve three-dimensional, transient incompressible flow problems. ZEPHYR3D includes an energy equation that allows coupled thermal/fluid problems to be solved with the limits of the Boussinesq approximation. It also includes an implementation of the Smagorinsky subgrid scale turbulence model, which allows ZEPHYR3D to perform large eddy simulation of turbulent flows. This report includes the mathematical and numerical basis for ZEPHYR3D, a user's guide, and several example/benchmark problems. These problems include flow over a backward-facing step, free convection in an enclosure, and the collapse of a mixed region in a stratified environment. 22 refs., 32 figs., 2 tabs.
