A qualitative analysis of the flow inside the closed test section of the Politecnico di Milano large wind tunnel in presence of rotor effects has been carried out with the ROSITA RANS solver. The rotor is represented as an actuator disk. The analysis of the results of the performed steady state simulations allow for the determination of the flow breakdown boundaries in terms of tunnel operating parameters. Some indications are provided on experimental measurements which may be used for an on-line detection of the flow breakdown itself.

Abstract
A qualitative analysis of the flow inside the closed test section of the Politecnico di Milano large wind tunnel in presence of rotor effects has been carried out with the ROSITA RANS solver. The rotor is represented as an actuator disk. The analysis of the results of the performed steady state simulations allow for the determination of the flow breakdown boundaries in terms of tunnel operating parameters. Some indications are provided on experimental measurements which may be used for an on-line detection of the flow breakdown itself.File in questo prodotto:
