Mach Number increase in the divergent portion of CD nozzle. How come mach number is highest in the throat? Is there some mistake?

If anyone is having trouble getting CFX to work,... you'll need to run CFX as administrator first, than map the file path for the workbench directory, using the folder ICON in the upper right corner, in my case it's R1 2024,... while CFX is running, start workbench and open the folder for the workbench project for this tutorial and it will load right up,... otherwise you get the error shown earlier.

In 13:55 when you enter pressure value below, it appears above as well after hitting apply. In my cfx pre it does not appear above. Do you know why???fyi: I use ansys 16.

Hi please can you do step by step exhaust fan simulation and Fan rotation animation for air

Many many thanks. What is NPR(nozzle pressure ratio)? and What is NPR in this simulation?
@LearnCAE2 жыл бұрын
Hi, I don't remember the NPR for this case. The main objective was to automate the process.

how is the flow greater at the throat than its upstream value in supersonic reginme??
@LearnCAE Жыл бұрын
By 'flow', do you mean mass flow or pressure or velocity, or any other parameter?

Amazing video!! Is it possible to create a parametric CFD analysis using ANSYS bladegen? I mean, inputting different geometries from Bladegen? Or turbogrid... Thanks a lot for the information!
@LearnCAE3 жыл бұрын
Hi, it is possible. But when it comes to blade design, you cannot easily parameterize the design trials. It is recommended to check and do it manually.

thanks for very informative video. By the way, could you make a video on how to produce a chart in CFD-post that have multiple design point. Example, pressure across the nozzle (or some piping) at multiple design point (let say design point 1, 2 and 3). Thank you
@LearnCAE4 жыл бұрын
Thanks for your comments. I will post a video regarding multiple design points and let you know. By the way, do you mean multiple back pressures or post processing data at different axial locations for same back pressure.

@@LearnCAE what I mean was, let say I have input variable which is inlet diameter, So my design point are inlet diameter 1, inlet diameter 2, and inlet diameter 3. In parametric design I can find the corresponding outlet pressure for those three cases from the parametric feature. However, I also want to find the pressure along the pipe/nozzle. How can I produce a XY plot, a graph of pressure vs length of pipe for those 3 cases (3 input diameter) simultaneously. For now, in post-cfd i can only produce the xy plot/graph of single line, for design point 1 (current) only. How do I do to get the result of design point 2 and 3 on the same plot. thank you.
@LearnCAE4 жыл бұрын
@@melanotictus To check all three results in single plot, I think you need to open all three result files in post processor and plot. If not, you can extract the data for all three cases and plot separately in excel or matlab or any other tool.

From which journal u r taking the boundary conditions?
@LearnCAE2 жыл бұрын
Hi, neither the model nor boundary conditions are taken from any journal. Only standard pressure boundary conditions are provided just to demonstrate parametric analysis steps.
