Cd nozzle design software

The applets are slowly being updated, but it is a lengthy process. This page shows an interactive Java applet to learn how nozzles work by changing the geometry and flow conditions which affect nozzle performance. With this software you can investigate how a turbojet or rocket nozzle produces thrust by changing the values of different factors that affect thrust. By changing the shape of the nozzle and the flow conditions upstream and downstream, you can control both the amount of gas that passes through the nozzle and the exit velocity.

There is another version of this program that has been modified for rocket nozzles. With the rocket version, you can specify a wider variety of propellant combinations. You can download a copy of the program to run off-line on your computer by clicking on this yellow button:. NOTE: If you experience difficulties when using the sliders to change variables, simply click away from the slider and then back to it. This effect is exactly the opposite of what happens subsonically. Why the big difference?

Because, to conserve mass in a supersonic compressible flow, both the density and the velocity are changing as we change the area. For subsonic incompressible flows, the density remains fairly constant , so the increase in area produces only a change in velocity.

But in supersonic flows, there are two changes; the velocity and the density. The equation:. To conserve both mass and momentum in a supersonic flow, the velocity increases and the density decreases as the area is increased. View More. Tweets by ApplMechEng. Review Article - Volume 6, Issue 6.

Abstract Tunnels have very severe air quality constraints that typically require good ventilation system. Tunnel ventilation Tunnels may require ventilation for a variety of reasons — For example to ensure an adequate air quality, to control the spread of smoke in case of fire, or to reduce temperatures to acceptable limits. CD nozzle De-Laval nozzle Convergent - Divergent nozzle is a tube that is pinched in the middle, making a carefully balanced, asymmetric hour glass shape.

Figure 6: Assembled CD nozzle model. The objectives of this research are: 1. Design, fabricate and analyze the performance of a C-D nozzle with a rotor and fan.

Rotor and fan to be mounted inside the CD nozzle at the throat area. Replace the cylindrical enclosure by CD Nozzle. Analyze the performance of both by comparison. Validate the results through experimentation. Design parameters There are various parameters that considered are explained below.

The parameter ranges for the inlet studied from various studies are given below Figures : CD Nozzle Inlet pressure is in the range of 2 bars. Inlet diameter is in the range of mm.

Cylindrical Duct Inlet pressure is in the range of 2 bars. Toggle Main Navigation. Search MathWorks. Close Mobile Search. Trial software. You are now following this Submission You will see updates in your followed content feed You may receive emails, depending on your communication preferences.
