| DESCRIPTION | Resistance and propulsion are key aspects of ship design and operation. This study-unit presents in some detail the various analytical and experimental considerations made in order to determine resistance of marine vessels. Moreover this is complimented by characterization of the design and selection process of the required propulsion system for marine vessels. This study-unit builds up on the fundamental theories and definitions developed in and Fluid Mechanics 1, 2 and 3. Study-unit Aims: The aim of the study-unit is to assess marine vessel resistance and propulsion in an interdependent fashion, building up on theories and definitions developed in Fluid Mechanics 1, 2 and 3. The study-unit is specifically aimed at those students who want to further progress a professional and/or academic career in maritime engineering . Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: Resistance - Analyse what constitutes ship resistance and list the different components. - Analyse dynamic similarity associated with ship modelling - Froude's law. - List the various parameters associated with hull form resistance design. - Analyse the wake field characteristics and deduce the required thrust for various applications. Propulsion - List and describe the various propulsor types - fixed, ducted, podded and azimuth, contra-rotating, overlapping, tandem, controllable pitch, surface piercing and waterjet propulsion. - Interpret propulsor design data. - Analyse and produce propeller performance characteristics in open water. - Analyse the effect of cavitation on open water characteristics. - Analyse propeller blade strength. - Analyse the effect of ventilation on ship propellers. - Describe the powering process by listing the various types of propulsion engines and their application in the maritime industry - diesel engines, gas turbines and steam turbines. 2. Skills: By the end of the study-unit the student will be able to: - Deduce the forms of ship resistance qualitatively and quantitatively primarily through analytical methods and some numerical applications. - Weigh the various considerations in hull form design and predict analytically and/or numerically resistance. - Predict the effective (towrope) power required by a ship at any speed. - Estimate hull efficiency from hull-propeller interaction effects. - Determine ship speed through water from sea trials and estimate power required from a propulsor. - Use and understand the inner working of a software package used for hull form design. - Enable independent study through research and assignment.
