sinusoidal oscillating airfoil simulation in CFX
Hello guys
I am trying to simulate a sinusoidal oscillating airfoil by CFX. The airfoil is NACA0012 and the oscillating center is 0.25 chord. the UDF for the oscilation is: --------------------------------------------------------------------- # include "udf.h" #define D 10.0 /* Amplitude */ #define K 0.026 /* Reduced Frequency */ DEFINE_CG_MOTION(airfoil, dt, vel, omega, time, dtime) { omega[2]=0.0174532*D*2.0*K*cos(2.0*K*time); } ---------------------------------------------------------------------- Can you help me and tell me how can I simulate this airfoil? I have no problem in modeling and mesh generation, but I don't know, where should I implement these equations? Waiting for you! Best |
I would not do this using a user function. This can be implemented easily in CEL and that is much easier. Have a look at the CFX tutorials for how to implement CEL expressions.
