VU-DUCT version 4.1
Educational tool to design or analyze subsonic wind tunnels or ducts.
Incompressible, inviscid analysis for rectangular, square, or
circular cross-sections, blow down or closed loop tunnels. Contains
moving probe. Multiple input and graphical output combinations.
Warning flags for violations of design assumptions.
VU-TURBO version 5.1
Educational tool to design and analyze a simple turbojet engine,
turbojet with afterburner, or two spool turbofan engine. Examination
tool included. One dimensional Breyton cycle analysis with flight
conditions, sizes, efficiencies, and materials limits specified
interactively by the user. Thrust, SFC, and various diagnostic
outputs presented graphically. T-s, p-v plots plus interactive
plotter. Printed output and restart file.
VU-INLET version 5.0
Design/Educational tool to predict flow conditions in external and
mixed compression, supersonic, rectangular inlets. Solves the
inviscid one-dimensional equations from NACA 1135 for oblique shocks,
expansion fans, normal shocks and reflected oblique shocks. Includes
subsonic duct model and inlet bypass and computes normal shock
position with change in engine airflow. Computes spillage mass flow
and drag and flags unstarts.
VU-SHOCKS version 4.1
Educational tool derived from VU-INLET which displays compressible
aerodynamics for three
flow problems: single compression wedge, two opposing wedges, or two
wedges in series. Solves for intersecting and reflecting shock waves.
Includes printed output, multiple types of graphical output, and
question and answer feature to lead students through interesting
problems in compressible aerodynamics.
VU-FOIL version 1.7
Educational tool to solve for two-dimensional, inviscid,
incompressible flow about airfoils. Shapes include flat plate,
elliptical cross-section, and Joukowski family of airfoils. Student
can vary thickness,
camber line, and
angle of attack.
Performs conformal mapping from flow around a circular cylinder with
circulation. Includes multiple types of graphical output, flow probe,
and lessons feature.
Flow Calculators version 2.4
Small calculators to compute multiple flow problems. No graphics.
Currently configured for isentropic flows, oblique shock, expansion
fan, normal shock relations, Rayleigh flow, Fanno flow, and standard
day atmospheric data. Multiple combinations of input accepted. NACA
1135 in your hand.
FoilSim version 1.0b
Educational package derived from VU-FOIL, but intended for high
school students. Computes the lift
around a basic airfoil
or a spinning baseball. Students can interactively vary any of the
design parameters. Outputs in either English or Metric units.
Contains interactive lesson.
Available in Unix, PC (Windows NT, Windows 95, Windows 3.1), and
Macintosh.
Coming soon
EngineSim
Educational package derived from VU-TURBO, but intended for high
school students. Allows students to interactive design, wind tunnel
test, and flight test turbojet and turbofan engines. Will be
available in either Unix or PC versions.
VU-MOC
Interactive method of characteristics solver. Allows students to
design rocket nozzles interactively. Intended for undergraduate
study.
VU-DIAMOND
Educational tool derived from VU-SHOCKS and VU-MOC which displays
compressible aerodynamics for a diamond airfoil
in a wind tunnel.
Intended for undergraduate study, a desktop wind tunnel, will include
multiple types of graphical output.
