Installing an energy saving device such as a pre-swirl duct (PSD) is major investment for ship owner and prior to order reliable prediction of the savings required. Currently there no standard how be carried out, possible alternatives are both model-scale tests in towing tanks with associated scaling procedures, well methods based on computational fluid dynamics (CFD). This paper summarizes CFD benchmark study comparing industrial state-of-the-art ship-scale predictions power reduction...
To estimate the powering and manoeuvring performance of ship in a real seaway, it is essential to accurately determine forces acting on hull, propeller, rudder their interaction effects when operating at an angle drift. The rotating propeller alters fluid flow around upstream hull downstream rudder. Likewise, non-zero drift or applied, significant crossflow generated across plane, changing wakefield actual propeller. A study conducted analyse hull–propeller–rudder benchmark KRISO Container...
In this paper, a modelling technique for simulating self-propelled ships in waves is presented. The flow modelled using RANS solver coupled with an actuator disk model the propeller. motion of ship taken into consideration definition region as well advance ratio RPM propeller controlled PID-controller constraints added on maximum permissible increase rate. Results are presented freely surging regular different put PID-controller. described method shows promising results and allows studying...
Development of novel hydrodynamic solutions to meet the demands for fuel efficiency future merchant fleet will require continuous innovation in Computational Fluid Dynamics (CFD) methods being used. This is especially true when considering development Energy Saving Devices (ESDs). Open-source CFD a way allow more researchers participate this process and accelerate innovation. paper presents an open-source framework conducting ship performance analyses within OpenFOAM suite. The helps...
Carbon Capture and Storage (CCS) is an increasingly popular scheme to mitigate CO2 emissions from large point sources (IPCC 2005). Thermal power plants account for a portion of the world's total are therefore most attractive target CCS. For typical thermal plant; process would involve capturing CO2, transporting it suitable location storage storing in manner that will ensure minimal leakage over very long period time. Due public concerns protests regarding onshore, offshore geological likely...
CFD is a useful tool for ship designers looking accurate predictions of the fuel efficiency achieved by certain combination hull, propeller and Energy Saving Devices (ESDs). Such are key to meeting ever-increasing demands reductions in emissions. However, simulations propeller-hull interaction can be very costly terms computational effort due need resolve unsteady flow around rotating propeller. A popular approach alleviate this cost, that has seen much practical use industry, body forces...
