The FreeFlow3D code can deal with three-dimensional incompressible free surface flows.
At the moment, the FreeFlow3D system has the following capabilities:
- It can simulate flows at high Reynolds numbers: a high order upwind
scheme for approximating the convective terms of the momentum equations
has been implemented into the code.
- It can solve 3D free surface tension dominated flows: an efficient numerical
method for computing the curvature has been included into code.
- It can deal with three-dimensional multi-fluid flows: a numerical
technique for dealing with 3D multi-phase flows has been added to the code.
- It can simulate 3D free surface flows of Generalized Newtonian fluids: recently
a constitutive equation for Generalized Newtonian fluids has been included into
the code. In this constitutive equation, the Cross model is used for computing
the viscosity.
- It can deal with 3D viscoelastic free surface flows: FreeFlow3D has been
extended to viscoelastic free surface flows governed by the Oldroyd-B constitutive
equation. The extension to flows governed by the Maxwell model and the
PTT (Phan-Thien-Tanner) constitutive equation is under development.
