Hi Guys,
I have to ask this any help would be great! I am looking to calculate the invariant map III-II for a RANS against the DNS data here: http://torroja.dmt.upm.es/channels/d...es/Re2000.prof however I need the Reynold's stress. Unfortunately I am unsure as to how to calculate this from the available data (the headers have confused me! <- annoyed in myself!) Best wishes, Jack |

Hi, just incase anyone else has this question they are the RMS (root mean square) values of u_i u_j, called the turbulence intensities by the authors (but intensity is typically divided by U) - so to get the Reynold's stresses simply square the values
ps. sbaffini - I thought they were Reynold's stresses at first too! |
