1.1 Program Capabilities

The ANSYS FLUENT solver has the following modeling capabilities:

• 2D planar, 2D axisymmetric, 2D axisymmetric with swirl (rotationally symmetric), and 3D flows

• Quadrilateral, triangular, hexahedral (brick), tetrahedral, prism (wedge), pyramid, polyhedral, and mixed element meshes

• Steady-state or transient flows

• Incompressible or compressible flows, including all speed regimes (low subsonic, transonic, supersonic, and hypersonic flows)

• Inviscid, laminar, and turbulent flows

• Newtonian or non-Newtonian flows

• Ideal or real gases

• Heat transfer, including forced, natural, and mixed convection, conjugate (solid/fluid) heat transfer, and radiation

• Chemical species mixing and reaction, including homogeneous and heterogeneous combustion models and surface deposition/reaction models

• Free surface and multiphase models for gas-liquid, gas-solid, and liquid-solid flows

• Lagrangian trajectory calculation for dispersed phase (particles/droplets/bubbles), including coupling with continuous phase and spray modeling

• Cavitation model

• Phase change model for melting/solidification applications

• Porous media with non-isotropic permeability, inertial resistance, solid heat conduction, and porous-face pressure jump conditions

• Lumped parameter models for fans, pumps, radiators, and heat exchangers

• Acoustic models for predicting flow-induced noise

• Inertial (stationary) or non-inertial (rotating or accelerating) reference frames

• Multiple reference frame (MRF) and sliding mesh options for modeling multiple moving frames

• Mixing-plane model for modeling rotor-stator interactions, torque converters, and similar turbomachinery applications with options for mass conservation and swirl conservation

• Dynamic mesh model for modeling domains with moving and deforming mesh

• Volumetric sources of mass, momentum, heat, and chemical species

• Material property database

• Extensive customization capability via user-defined functions

• Dynamic (two-way) coupling with GT-Power and WAVE

• Continuous fiber module (documented separately)

• Fuel cell modules (documented separately)

• Population balance module (documented separately)

ANSYS FLUENT is ideally suited for incompressible and compressible fluid-flow simulations in complex geometries. ANSYS FLUENT's parallel solver allows you to compute solutions for cases with very large meshes on multiple processors, either on the same computer or on different computers in a network. ANSYS, Inc. also offers other solvers that address different flow regimes and incorporate alternative physical models. Additional CFD programs from ANSYS, Inc. include CFX, ANSYS Airpak, ANSYS Icepak, and ANSYS POLYFLOW.
