Ideal Flow Machine: An educational java applet for studying elementary ideal flow, version 4.0 |
|
|
Author:
|
|
William Devenport |
|
Description:
|
|
The Ideal Flow Machine applet demonstrates elementary ideal flow in which a fluid (liquid or gas) moves when the effects of compressibility and viscosity are negligible. Large parts of the flows past ships, submarines, cars and light aircraft are closely ideal. The applet gives students an environment where they may experiment with and visualize elementary two-dimensional ideal flows. |

Description:
|
|
A set of java
applets for computing and solving boundary-layer
problems . These include WALZ, ILBLI, CLBL and
WALZHT for laminar boundary layers and MOSES,
ITBL, CTBL and MOSESHT for turbulent boundary
layers. Applets WALZ, MOSES, WALZHT, MOSESHT
employ integral methods while ILBLI, CLBL ITBL,
CTBL use finite difference methods. WALZ,
ILBLI, WALZHT, MOSES, ITBL and MOSESHT are for
computing incompressible flows while CLBL, CTBL
are for compressible flows. WALZHT, MOSESHT,
CLBL and CTBL have the capability of computing
thermal boundary layers. |

William J. Devenport |
|
Description:
|
|
An educational java applet for computing the standard relations for compressible flow of a perfect gas. The calculator is intended to provide a faster more convenient alternative to printed tables and charts (e.g. NACA Report 1135). Three sets of included namely, Isentropic Flow Relations, Normal Shock Relations and Oblique Shock relations. |

Vortex Panel Method Applet , Version 1.0 |

|
Author:

|
William J. Devenport |
|
Description:
|
|
The Vortex Panel Method Applet is a computational tool for students studying the aerodynamics of airfoil sections, and in particular, ideal flows in which the effects of compressibility and viscosity are assumed negligible. Ideal flow is often the first type of fluid motion that student engineers and scientists study, because it is the simplest. Large parts of the flows past ships, submarines, cars and light aircraft are closely ideal. |

Real Gas Shock Calculator |
|
|
Author:

Matthew MacLean |
|
Description:
|
|
This applet calculates the property variations across a normal or oblique shockwave under two sets of assumptions. The first choice is the standard assumption of a calorically (and thermally) perfect gas. The gas can be any that meets the assumptions provided The gas constant and specific heat ratio are known. The second option is for standard equilibrium air at densities from 1,000 amagats to 1e-7 amagats and temperatures up to 25,000 K. This analysis accounts for real gas effects of a standard mixture of species in air including dissociation and ionization. This analysis is generally quite accurate for values within the stated density range, but can only be used with air. The program provides many options for specifying upstream properties and provides quick calculation. The output can be summarized to be copied and pasted into a word processor, and the applet provides a platform-independent, easy-to-use interface. |

Tom Benson. |
|
Description:
|
|
This program lets
you study how the properties of the atmosphere
change with altitude. You can study the
atmosphere of either the Earth or Mars. The
equations used in this program are taken from
the ICAO standard day model for the Earth and
from some curve fits of the Martian atmosphere
gathered by the Global Surveyor spacecraft.
Using the airplane graphic you can select an
altitude, or you can type an altitude into the
input box. |

A Method for Calculating Transient Surface Temperatures and Surface Heating Rates for Hish-Speed Aircraft |
|
|
Author:

|
Robert D. Quinn,Leslie Gong |
|
Description:
|
|
This report describes a method that can calculate transient aerodynamic heating and transient surface temperatures at supersonic and hypersonic speeds. This method can rapidly calculate temperature and heating rate time-histories for complete flight trajectories. Semi-empirical theories are used to calculate laminar and turbulent heat transfer coefficients and a procedure for estimating boundary-layer transition is included. Results from this method are compared with flight data from the X-15 research vehicle, YF-12 airplane, and the Space Shuttle Orbiter. These comparisons show that the calculated values are in good agreement with the measured flight data. |
