Stato dell'arte sulle eliche di superficie
Reverse cycles allow environmental and waste heat to be converted into process heat, providing energy in an efficient and environmentally sustainable manner. Systems that perform such cycles are called heat pumps or chillers, depending on whether the useful effect sought is heating or cooling, respectively. Only the term "heat pump" will be...

The present paper discusses the application of sponsons to a twin-screw passenger ferry. Four different versions of sponsons have been designed and tested in a towing tank. The results are compared to the power predictions obtained through traditional methods for twin-screw merchant ships.
Nel presente lavoro vengono presentati i risultati di misure del campo di velocità a valle di un modello di elica medio-veloce per propulsione navale effettuate mediante anemometro laser- Doppler nel tunnel di cavitazione dell'Università di Genova. Le misure presentate sono state effettuate in corrispondenza di diversi piani normali all'asse di...
The ISO 12217 Standards for Small Craft Stability and Buoyancy enables the determination of the limiting environmental condition for which an individual boat has been designed. They are prescriptive rules based on a deterministic approach taking into consideration the design parameters assumed significant for the assessment of stability i.e....

In recent years an increasing interest towards innovative techniques to be applied in usual experimental facilities has grown. From cavitation tunnel point of view, attention has been given to measurement of dimensions of propeller cavitation bubbles. The need arises from the increase in ship performance and environmental/comfort requirements,...

Experimental tests have been performed on a systematic series of surface piercing propellers with varied number of blades (4 and 5) and pitch ratio (from 0.8 to 1.4). Some aspects of scaling the performance of this kind of propulsor have been investigated. Influence of depth of immersion and shaft inclination is discussed and results for...

Experimental tests have been performed on a systematic series of surface piercing propellers with varied number of blades (4 and 5) and pitch ratio (from 0.8 to 1.4). Influence of depth of immersion and shaft inclination is discussed and results for variations in these parameters are presented. Regression equations are given describing the...
