Acoustic Characteristics of Laminar-Turbulent Transition in a Flat Plate Based on PSE and FW-H--- Low Noise Propeller Design Technology for Urban Air Mobility(UAM)--- Evaluation of different FW-H surfaces and modal decomposition techniques for the acoustic analysis of UAV propellers through detached...
The performance of wind turbines has improved significantly, by a factor of 63%, according to the results. To sum up, a tip-speed ratio of 2.5 significantly impacts but should be considered under various working circumstances. Cavitation in a Cross-Flow Turbine In this study, cavitation in ...
The numerical simulations of open water performance of marine propeller E779A are carried out with different advance ratios to verify the numerical simulation method. Results show that the thrust and the torque are in good agreements with experimental data. The grid independent inspection is applied ...
More advanced sound analysis methods that have been utilized in other industry sectors or academia have not been assessed regarding their applicability in combination with realistic propeller-hull combinations within the context of numerical simulations, which is the aim of this study. For this purpose...
This study presented the results of a computational study of cavitating flows of a marine propeller with energy saving equalizing ducts. The main purpose of the study was to estimate the cavitating flows around a propeller with a duct, and to investigate the interaction between a duct and a pro...
Lee et al. [10] also performed a study on the effect of rope cutters on the vibration of the propeller shaft. The results of the study showed that the effect of the cutting action on the propeller shaft vibration was found to be very small. Therefore, installing a rope cutter on the ...
