RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and heat transfer and the effect of surface roughness on near wall flow are considered by this program, it can be used for engineering calculation of the friction drag and heat transfer coefficients on airfoil surface. ...

...Menter's k-omega SST (short for Shear Stress Transport) model is probably the dearest turbulence model in aerodynamics community. It is a blend of k-omega and k-epsilon model. It's popularity is not diminishing since it's being used in new RANS/LES hybrid models like DES (Detached Eddy Simulation) too. My wish was to made available to wider community a simple implementation of this model. First I will upload only 2D code, and in the future I plan to upgrade CAFFA to unstructured 3D version.

This is an implementation of the "Random Agent Networks" model, described in Gershenson, C. (2006). Towards Self-organizing Bureaucracies. Submitted (ECCO working paper 2006-03). http://uk.arxiv.org/abs/nlin.AO/0603045
