  OpenFOAM is a free, open source CFD software package developed by OpenCFD Ltd at ESI Group and distributed by the OpenFOAM Foundation . It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics   EasyCFD_G is a computational fluid dynamics (CFD) software tool for the numerical simulation of two-dimensional and 3D axisymmetric fluid flow in a boundary fitted mesh. Numerical Calculation of Fluid Flow and Heat Transfer in 2D and 3D axisymmetric domains Home Examples Contact and Download Other Software · Laminar or turbulent flow · Isothermal or non-isothermal flow · Steady-state or transient flow · Structured and unstructured mesh generation · k-e and SST k-w turbulence models
  OpenFlower is a free and open source CFD code (for Linux and Windows) mainly intended to solve the turbulent incompressible Navier-Stokes equations with a LES approach. It can deal with arbitrary complex 3D geometries with its finite volume approach.   NaSt3DGP is an implementation of a solver for the incompressible Navier-Stokes equations in three dimensions. It is based on a Chorin type projection method. The main features of NaSt3DGP are: spatial discretization by 2nd order finite differences on a rectangular, non-uniform, staggered mesh convective term: higher order upwind schemes (VONOS, SMART), central differences (2nd order), simple upwind (1st order) 2nd order Adams-Bashforth scheme for the time discretization boundary conditions: slip, no slip, periodic, inflow, outflow (Neumann, convective, natural) 
  OpenFVM is a general open source three-dimensional Computational Fluid Dynamics (CFD) solver (for Linux and Windows). It uses the unstructured finite volume method to simulate non-isothermal transient flow. Gmsh is used for pre- and post- processing.
