Testing of global control performance for open water channels
2011 International Conference on Networking, Sensing and Control, 2011Open water channels are used to distribute irrigation water to farms and they are large scale systems consisting of many interacting subsystems. The operational objective is a trade-off between a high level of service to farmers and a good water delivery efficiency, and it is well known that automatic control systems can help in achieving these ...

Journal of Hydrodynamics, 2006
The paper presents a validation study of a RANS prediction of open water characteristics of a highly skewed propeller in full range advance-ratio. Computational results are compared with open water data, and extensively validated at one loading with paint test, cavitation inception test and PIV measurements.

Open Water Performance of a Feathering Propeller
SNAME 13th Propeller and Shafting Symposium, 2012In recent years, a number of propeller designs have been developed that aim to reduce the resistive characteristics of sailboat propellers when not in use. One of the more common of these designs is the feathering-blade propeller. Feathering propellers accomplish this decrease in resistance by rotating each blade to a pitch of 90 degrees, parallel to ...

The scale effects on the open water performance of a pump-jet propulsor
Journal of Marine Science and Technology, 2021In this work, the scale effects on the open water performance of a pump-jet propulsor (PJP) with pre-swirl stator are considered and implemented based on systematic numerical calculations. With considering the effects of mesh density and time-step size, the unsteady open water performance at the design advance coefficient both in full scale and model ...

Influence of bearings on the open water performance of a rim-driven thruster
Physics of Fluids, 2023The rim-driven thruster (RDT) represents an important advance in the marine propulsion system. Its innovative structure introduces several outstanding advantages but also rises some major challenges. This paper aims to investigate the influence of bearings on the rim-driven thruster in terms of hydrodynamic performance with computational fluid dynamics.

Cardiac performance after an endurance open water swimming race
European Journal of Applied Physiology, 2019Endurance exercise competitions have shown a transient negative effect on global right ventricular (RV) performance. Most published studies are based on terrestrial sports. The aim of our study was to evaluate the cardiac effects after an open water swimming race.We evaluated 33 healthy swimmers (mean age 40.9 ± 7.2) participating in a 9.5 km open ...

NUMERICAL ANALYSIS OF FLOATING BOOM PERFORMANCE IN OPEN WATERS
Coastal Engineering 2008, 2009Previously proposed numerical models of oil containment booms have a series of shortcomings. The boom is generally considered as a fixed object and in the few cases in which the main boom motions are implemented into the model, the containment is not taken into account.

Performance measures and models for open‐water integrated multi‐trophic aquaculture
Reviews in Aquaculture, 2018AbstractQualifying and quantifying nutrient flows within open‐water Integrated Multi‐Trophic Aquaculture (IMTA) systems is necessary to determine transfer efficiencies and to assess overall system performance. There are numerous empirical performance metrics, such as spatially defined growth and nutrient sequestration, which may have application.
