Hi everyone!

I am working on my thesis project, related to reduction of drag in a transonic flow case over a NACA0012 airfoil. I am already late for my project so seriously need some help.

Does FLUENT predict the shock wave location by itself for a given flow condition (& BCs)?? I read that the transition point can somehow be fixed. If so, how is it done? Plz help with detailed description if possible.

Thank you in advance.

Cant you just plot contours or pressure vs. X position and see where there are discontinuity in the plot

Hello,

Update: I managed to calculate the shock-wave position, though for a 2D aerofoil, following instructions in this tutorial,

https://confluence.cornell.edu/displ...ow+Over+a+Wing

I used flow parameters such as AOA, Mach Number and Reynolds Number as given in a report of NASA, based on experiment results (Ref: C.D.Harris). But my simulation results (x vs Cp plot) did not match those given in the report. The shock-wave location was more upstream in my results for Mach numbers 0.75 & 0.8 (those are the only two I tried). Also the lower surface maximum Cp was significantly higher (in my simulation) than actual report values.

Kindly advice on what should I do now.

Thanks.
