Virtual Wind Tunnel
analyzes 2-D and axisymmetric subsonic,
transonic, and supersonic flow (Mach 0.1 to 10) over multi-element configurations on a Cartesian cut-cell mesh.
Flow visualization is provided through color maps of local Mach number, density, pressure, and temperature, including streamline plots.
An aerodynamic force line instantly reveals the center of pressure of any configuration.
can model vehicles in ground effect through a 2-D simulation of flow along their centerline. Bodies of revolution
such as spherical projectiles, bullets, space
capsules, or rocket nozzles are tested in axisymmetry mode. Airfoil
cascades can be set up for compressor or turbine blade profile analysis, and both supersonic ramp and spike
inlets can be modeled.
is based on a finite volume description of the unsteady Euler equations and can capture both steady and moving shock waves.
A solution is marched in time from an instantaneous acceleration of the flow and converges
to steady or periodic
state within an hour on a system with minimum requirements.
On systems with multi-core processors or CUDA enabled NVIDIA graphics cards, a wind tunnel test will
complete in minutes.
runs out of Microsoft Windows through simple "point and click" operations, which are outlined in an easy-to-follow tutorial.
A two-part narrated instructional video shows its simplicity. The software has been validated through experimental data in 2-D (NACA
airfoil) and axisymmetric (G7 bullet) flow studies and has been put to the test by a diverse number of
clients in academia, government, and industry.
is available in two editions. The educational edition of the Virtual Wind Tunnel has a flow resolution of
(480,000) cells, whereas the professional edition runs at
tunnel resolution (1 million cells) for more accurate results. The professional edition can run multiple tests in a batch
and generate a summary text file of all the relevant aerodynamic data.
is downloaded in seconds through a 1 Mbit/s internet connection. The 2.6 MB installation file
is a compressed, self-extracting executable, which will guide you through the setup of the program and all supporting files.
Each edition of the software can be run free for a trial period of three days. There is no obligation to buy!
Multi-user and multi-year licenses are available at a discount rate.
