XFOIL is an interactive program for the design and analysis of subsonic isolated airfoils.Given the coordinates specifying the shape of a 2D airfoil, Reynolds and Mach numbers, XFOIL can calculate the pressure distribution on the airfoil and hence lift and drag characteristics.
The purpose of this software is the design and aerodynamic simulation of wind turbine blades. The integration in XFOIL allows for the user to rapidly design custom airfoils and compute their performance curves, Extrapolating the performance data to a range of 360° Angle of attack , and directly integrate them into a wind turbine rotor simulation.
ESP-r main menu and an exemplar model. ESP-r is a research-oriented open-source building performance simulation software. [1] [2] [3] ESP-r can model heat flow in thermal zones, fluid flow using networks or CFD, electrical power flow, moisture flow, contaminant flow, hygrothermal and fluid flow in HVAC systems, as well as visual and acoustic performance aspects within a modeled energy system ...
A computer simulation of high velocity air flow around the Space Shuttle during re-entry A simulation of the Hyper-X scramjet vehicle in operation at Mach-7. The fundamental basis of almost all CFD problems is the Navier–Stokes equations, which define many single-phase (gas or liquid, but not both) fluid flows.
PhET Interactive Simulations is part of the University of Colorado Boulder which is a member of the Association of American Universities. [10] The team changes over time and has about 16 members consisting of professors, post-doctoral students, researchers, education specialists, software engineers (sometimes contractors), educators, and administrative assistants.

Potential-flow streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. The flow is two-dimensional and the airfoil has infinite span. In fluid dynamics, potential flow or irrotational flow refers to a description of a fluid flow with no vorticity in it.
Thin airfoil theory assumes the air is an inviscid fluid so does not account for the stall of the airfoil, which usually occurs at an angle of attack between 10° and 15° for typical airfoils. [20] In the mid-late 2000s, however, a theory predicting the onset of leading-edge stall was proposed by Wallace J. Morris II in his doctoral thesis. [ 21 ]
FlightGear Flight Simulator (often shortened to FlightGear or FGFS) is a free, open source multi-platform flight simulator developed by the FlightGear project since 1997. [ 4 ] David Murr started this project on April 8, 1996.
