...A. S. Bahaj; L. E. Myers; R. I. Rawlinson-Smith; M. Thomson An experimental and theoretical investigation of the flow field around small-scale mesh disk rotor simulators is presented. The downstream wake flow field of the rotor simulators has been observed and measured in the 21m tilting flume...

...) conservative scheme is used to solve the governing equations written in curvilinear coordinates and the k-ɛ turbulence model is used to simulate the turbulent flow in the wake of the body. The cylinder is supported by a spring and a damper and free to vibrate in the transverse direction. In previous work...

...Lars C. Gansel; Thomas A. McClimans; Dag Myrhaug Experiments were carried out to measure forces on and wake characteristics downstream from fish cages. Cylinders made from metal mesh with porosities of 0%, 30%, 60%, 75%, 82%, and 90% were tested in a towing tank. The drag force was measured...

...J. Baltazar; J. A. C. Falcão de Campos A low order potential based panel code is used to analyze the flow around the blades of a horizontal axis marine current turbine. An empirical vortex model is assumed for the turbine wake, which includes the variation of pitch of the helicoidal vortices...

...Robert D. Blevins, Ph.D.; Jean-Francois Saint-Marcoux, Dr. Ing.; Mason Wu Measurements have been made of two dimensional motion of an elastically supported circular cylinder in the wake of a fixed upstream cylinder. The experiments were made in a water flow channel with 6.35 cm ( 2.5 in. ) diameter...

...S. El Lababidy; N. Bose; P. Liu; F. Di Felice To provide experimental data on the hydrodynamic characteristics and features of dynamic positioning (DP) thrusters under variable operating conditions, wake measurements were performed on a DP thruster model using 2D laser Doppler velocimetry (LDV...

...Robert D. Blevins, Consultant A model is developed for the steady fluid forces on a cylinder that is in the wake of a parallel, upstream cylinder in cross flow. The fluid forces are determined by correlating experimental data with an asymptotic model of the wake. This allows both lift and drag...

..., an understanding of the flow around the thrusters is of great practical interest. Despite this interest, there is lack of knowledge in the description of the hydrodynamic characteristics of a ducted thruster’s wake at bollard pull and low advance coefficient values. This work was aimed at providing detailed data...

...Wusheng Wu; Shan Huang; Nigel Barltrop The static equilibrium position and its associated dynamic stability of a cylinder situated in the wake of an upstream cylinder is investigated in this paper. Both the upstream and downstream cylinders are elastically mounted on springs to allow for streamwise...

... case, one can define a free-wave spectrum that is valid for all lateral positions and distances astern of the vessel. The free-wave spectrum contains a complete description of the Kelvin wake, and wave elevations at any far-field position can be readily calculated once the spectrum is known...
