Numerous studies based on experiments or computations have been carried out to investigate propeller open water characteristics. Most studies only consider the case of a propeller in straight ahead flow. However, under real conditions, a working propeller operates behind a ship usually in a complex wake, so that the propeller shows quite different hydrodynamic performance.
In this paper, the cavitating performance and open water performance of the SMP’15 propeller are numerically simulated using the flow solver ISIS-CFD.

Turbochargers are currently ubiquitous in automobiles. It is nearly impossible to find a new Diesel vehicle without turbocharging and direct injection. Gasoline cars have been also following suit for the past few years. Regulations are pushing for lower emissions and the way to achieve this has been downsizing and using turbocharging to offset the lower power density of a smaller motor.

The goal of this case is to optimise the shape of the propeller, but at the same time reduce the impact of manufacturing variability on the performances. This is of particular importance for marine applications, where even small performance drops during operation can have significant financial impact through increased operational costs. A standard (deterministic) optimisation is compared with a robust optimisation, taking these manufacturing uncertainties into account.

Valve | FSI | AGR | Overset Grid | OMNIS™/Hexpress | FINE™/Marine
Check valves are commonly implemented in piping systems in order to control the fluid flow and to avoid reverse flows, since these can degrade the performance of the system and can cause structure failures. The opening of the valves is mainly caused by the hydraulic force which is the sum of viscous and pressure-based forces acting on the discs. A dual-disc check valve relies primarily on the spring force for closure. Here, the transient flow through a typical dual-disc check valve is investigated in FINE™/Marine and the opening process of the valve is analysed.

This paper investigates the hydrodynamic performance of a classic wooden powerboat, the RIVA Junior, using CFD and driven by an environmentally friendly electric motor. The original hull shape is parametrised for variation in an optimisation chain: several operating points (speeds, displacements) and various objectives are considered, aiming to model different operational profiles of an electric propulsion. The goal is to derive hull design trends for both highest speeds for a given power, but also maximised range using the limited electric energy, and of course the trade-offs in between.
