Paper presented at the The 30th International Ocean and Polar Engineering Conference, October 11–16, 2020
Paper Number: ISOPE-I-20-2130
... ABSTRACT An underwater robot usually consists of a main body and several control ducted propellers. In numerical simulation on the hydrodynamic behavior of underwater robot at a high speed motion in large computational domain with CFD approaches, some computational failures may occur due to...

Paper presented at the The 29th International Ocean and Polar Engineering Conference, June 16–21, 2019
Paper Number: ISOPE-I-19-099
... ABSTRACT In this paper, a systematic method to design marine ducted propellers is presented for a given duct shape and design conditions to achieve the highest efficiency while avoiding cavitation. The duct is solved by the 2D-axisymmetric Reynolds-Averaged Navier-Stokes (RANS) method and the...

Paper presented at the The 26th International Ocean and Polar Engineering Conference, June 26–July 2, 2016
Paper Number: ISOPE-I-16-053
... Abstract A numerical method to observe thrust behavior of a ducted propeller attached in an underwater vehicle under the influence of flow field of the vehicle's main body is proposed, the thrust characteristics of ducted propeller and the velocity distribution around the propeller when the...

Paper presented at the The Twenty-fourth International Ocean and Polar Engineering Conference, June 15–20, 2014
Paper Number: ISOPE-I-14-510
... Abstract QCM has been applied to open-water thrust and torque predictions of the ducted propellers with different positions of the propeller and duct. The QCM results are in good agreement with the experimental data of the propellers positioned inside a duct. The results of propellers in the...

Paper presented at the The Twenty-second International Offshore and Polar Engineering Conference, June 17–22, 2012
Paper Number: ISOPE-I-12-683
... developed vortex lattice method (VLM) is coupled with Renolds Averaged Navier Stokes (RANS) based Computational Fluid Dynamics (CFD) tools, in order to predict the hydro-dynamic performance of ducted propulsion systems. The analysis of the performance for ducted propellers subject to steady and unsteady...

Paper presented at the The Twentieth International Offshore and Polar Engineering Conference, June 20–25, 2010
Paper Number: ISOPE-I-10-036
... ABSTRACT The ducted propeller is widely used as a propulsor in submarines, torpedos, UUVs (unmanned underwater vehicles), underwater robots, and DPDs (diver propulsion devices) because of its high propulsive efficiency. Its merits also include collision protection, efficiency enhancement...

Paper presented at the The Tenth International Offshore and Polar Engineering Conference, May 28–June 2, 2000
Paper Number: ISOPE-I-00-152
.... INTRODUCTION Ducted propellers have been used for many years in the marine industry to both protect the propeller from damage, and to improve upon the propeller efficiency under certain load conditions, Consequently a wide range of tests have been carried out on the units and much performancee data has been...

Paper presented at the The First International Offshore and Polar Engineering Conference, August 11–16, 1991
Paper Number: ISOPE-I-91-143
... ABSTRACT: This paper presents the key results of a comprehensive study into the nature and magnitude of the mechanisms which contribute to the loads on both open and ducted propellers in the presence of ice. Both model test and full scale trials measurements and visual observations were...
