THE MACYL6 HYDRODYNAMIC CODE: A NUMERICAL METHOD FOR CALCULATING INCOMPRESSIBLE AXISYMMETRIC TIME-DEPENDENT FREE-SURFACE FLUID FLOWS AT HIGH REYNOLDS NUMBER

Abstract

A computer code was developed for solving incompressible two- dimensional axisymmetric time-dependent viscous fluid flow problems involving up to two free surfaces. Heuristic models for turbulence are employed to extend the method to indefinitely high Reynolds number. Scalar quantities (heat and solute concentrations) are also followed, and the fluid may be slightly nonhomogeneous in the Boussinesq approximation. The method is a second-order space, forward time explicit finite-difference scheme. Free surfaces are treated using the MAC ('Marker-and-Cell') technique.
