Simulations - Results


we follows similar steps to the first part in order to get the results,

We can create a line probe to get the velocity values on this line,

Derived $\rightarrow$ Parts $\rightarrow$ New Part $\rightarrow$ Probe $\rightarrow$ Line...

We plot the streamlines afterwards,

Velocity field is represented in the following figure for an upstream velocity of $10m/s$

A zoom on the nacelle:

We plot here the velocity measured by the sensor $s_1$ as a function of the velocity upstream the rotor:

  • Position of sensor $s_1$: $0,5\ m$ above the pod and $0,5\ m$ from the end,
  • calibration equation: $y=-0,176+1,044 x$
  • the residual norme for this method: $1,6\ .10^{-4}$.

 One can notice that the residual is very tiny, because we didn't simulate the rotor which is the most important source of turbulence.
 Once we simulate the rotor, one can plot the calibration equation for different points above the nacelle, and find the point with the less residual norme.
