Wake simulation of a marine propeller

Résumé

The flow past a rotating marine propeller is analyzed with the aim of establishing capabilities of different turbulence modelling approaches. Two RANSE models are used: the k-ω SST of Menter and an anisotropic two-equation Explicit Algebraic Reynolds Stress Model (EARSM). A DES approach based on the k-ω model is also used. The numerical simulations with the RANSE models give a good prediction of the thrust and torque. However, the wake of the propeller is too dissipate and the instabilities of the wake are not predicted. On the contrary, DES approach can allow to capture the evolution of the tip vortices and predicts the onset of instabilities in the wake.
