Hi there,
I am going to produce a box of isotropic turbulence and I have the following questions: 1-What should I use for initial conditions? (This is my main problem becauas I know we can not just set some sort of random numbers) 2-since it will be decaying and I want to stop it at a certain turbulence intensity, how should I know that I should stop the run to get my desired intensity? 3-Can I have a box with any aspect ratio? (Since I want to feed it as a precursor, I want it to have the same dimension as my main simulation inlet)? I'appreciate to hear you useful comments. |

Check:
http://torroja.dmt.upm.es/turbdata/a...hapter3/HOM02/ They provide a velocity field that could be useful for your initial field. Cheers, Mary |
