For calculating the velocity field around the car model(case 2) in Re=1.600.000 (U=96m/s)
in an open wind tunnel. Would you recommend LDA or PIV? LDA is surely more difficult to set up and to get the whole 3D results in transverse grids along the 250mm model. That is why i was thinking about 3D...
I am thinking of using PSP (pressure sensitive paint). I know that this is used mainly in low speed flows (automotive industry) and steady flows but i wonder if i could use it in unsteady transonic conditions. The Mach number is 0.92 and the Strouhal number is 0.01 leading to a frequency of...
I think that the PIV system is the best option. What seeders would you use?
Would you advise thermometry as an option for the car? Could you please explain the "thread on a stick" option?
Thank you very much
Hello everyone,
the forum looks great and I have been reading it for a long time, but I have only registered.
I am writing this post because I have to analyse two flow fields in a wind tunnel.
1) The first flow is generated from a helicopter blade, with Re=2000000, Mach=0.92 and...
