Does anyone know of a free DNS code which I can download. It needs to be in cylindrical coordinates because I would like to perform a DNS simulation of a coaxial jet ?

(1). Would it be easier to look for DNS simulation results of coaxial jet?

no, I want to run the DNS myself. And by the way, DNS stands for direct numerical simulation. I've designed a new model and I would like to tune it for a coaxial jet. I'll interpolate the DNS data onto my RANS grid. With this I can see how the turbulence model is performing with the the correct velocity field etc...

Check with Turbulent research center at Stanford University. They are doing a lot of DNS Calculations.

I would check the Stanford cite but their web page for Center for Turbulence Research has been down for a while. Besides, I've search their cite several times in the past and I have never seen any source code access.

Hi D.R. Jones,

I guess what you are looking for is something like a link to free softwares in CFD;

Why don't you try this one:

http://www.math.psu.edu/dna/CFD_codes_p.html

There is there a whole bunch of hydro codes in multidimensions and different geometries able to treat turbulence too.

Let us know if this works. If it doesn't I can give you two more links to astrophysical CFD codes that should be suitable for DNS.

I hope this helps,

Patrick (D.R. Godon)

hi there,

you can download a Homogenous isotropic turbulence code (DNS and LES, fractional step, finite difference...) at the following address: http://mae.uta.edu/~lund (at the bottom of the page) It's not cylindrical, but anyway, you can modify the code to fit your needs.

I hope this help. Sincerely,

Frederic Felten CFD Laboratory. UT Arlington, TX, USA. http://utacfdb.uta.edu/

Download the flux-corrected transport modules from:

http://www.lcp.nrl.navy.mil/lcpfct

there is a link there somewhere. You can do all the DNS you want with those. Allthough you will have to add all the viscous stress terms yourself.

Dan.
