| الوصف: | An acceleration maneuver may have critical operating phases where the propeller is subjected to unsteady flow conditions in addition to gradual or sudden changes in the number of revolutions per second (RPS). In the present study, a control model is developed to assist the acceleration maneuver of underwater vehicles in calm water under various operating conditions, in which the increase in propeller speed is precisely controlled to ensure the avoidance of tip vortex cavitation and to enable a reduction in the non-cavitating noise radiated by the propeller during the acceleration maneuver. As a test case for the study, the DARPA SUBOFF geometry (Defense Advanced Research Projects Agency) in combination with the CNR-INM E1619 propeller is selected. The numerical simulations are conducted using the RANSE-solver STAR-CCM+. The hybrid method, which combines CFD and P-FWH is applied to calculate the acoustic pressure and estimate the propeller radiated noise. The provided control model shows that the inception of the tip vortex cavitation can be avoided during the acceleration maneuver. In addition, the noise radiation can be reduced when the control model is activated. |
