Quasi one dimensional nozzle flow
 
Dear all, I am a beginner in CFD. I am now trying to solve the quasi one dimensional nozzle flow using upwind schemes. I have read some books but still do not know how to start a program. Where can I have the fortran code for it so that I can study it from the very beginning. Thank you very much for your information

Best regards

There's a book: 'Computational Fluid Dynamics' by John Anderson, and he talks you through how to write a quasi 1-D code for a convergant-divergant nozzle. He lays out how the program can be written, implementing CFL numbers, shows how the results should look after the first timestep, and graphs the final results so you can compare. When I did some early programming, this was the best book I found for it. Hope it helps, Steve.

Great, is it using simple the correlation of A(x) and Mach # to solve the problem or is it using FVM method?

Thank you for your information

It uses a finite difference MacCormack scheme. The scheme is also discussed in detail in that book and in a very simple language.

yeah I found an online version of that book

http://www.scribd.com/doc/7504698/Computational-Fluid-Dynamics-the-Basics-With-Applications-Anderson-J-D

The electrical pages 302-390 talks about this problem detailly.

But it's really too hard for me because I have only 2 days to do my homework. So I simply dropped that course. Thank you al the same.
