The objective of this validation case is to check the sensitivity of vibroacoustic results to the rotational direction and the relative rotor to stator position at time t=0. The acoustic noise should not depend on these parameters, and any variation represents numerical errors.

Results

Sensitivity of MANATEE vibroacoustic model to the rotational direction and the relative rotor to stator position
Sensitivity of MANATEE vibroacoustic model to the rotational direction and the relative rotor to stator position

The simulations with different rotor positions and rotation directions show that the numerical error is less than 0.2 dB.
