NAME 423: Power and Propulsion Systems

3.00 Credit. 3 hrs/wk.

Prereq. NAME 323


Ship power and propulsion systems. Steam, diesel and gas turbine power plants together with speed reducers and propulsors. Propulsors- fixed pitch, controllable pitch, tandem, contra-rotating, supercavitating, ducted, vertical axis and water jet. Comparative studies of different propulsors.  Energy efficiency design index (EEDI) and its application according to IMO.


Computer Aided Hull Design

In principle, students should just get familiar with some specific design applications, such as Rhino3D, Maxsurf, Foran,... But a thorough knowledge of their capabilities comes from learning at least the algorithms that lie behind the application, even if the students are not to become developers themselves.

NAME 323: Resistance and Propulsion of Ships

This course covers following topics:

Phenomena resisting the motion of ships. Resistance due to friction, wave making, form, appendage, wind and waves, squat, blockage and shallow water effects. Estimation of powering using methodical series and statistical methods. Advantageous effects of hull form changes- bulbous bows. Asymmetric sterns and optimum trim for ships in ballast.

Screw propeller geometry. Momentum and blade element theories. Propellers in open water, propeller coefficients and design charts. Hull propeller interaction- wake, thrust deduction and relative rotative efficiency. Propeller cavitations. Propeller blade strength. Screw design according to circulation theory for uniform and non-uniform wake. Speed trials and service performance analysis.

NAME 223: Marine Hydrodynamics

Flow of an ideal fluid: equation of continuity, streamlines, streak lines and path lines, two-dimensional flow patterns, rotational and irrotational flows, vorticity, velocity potential functions, stream functions, Euler’s equation of motion, Bernoulli’s equation, velocity and pressure distribution. Uniform flow, irrotational vortex, circulation, source, sink and doublet, flow past a half body, cylinder and rankine body, virtual mass and Magnus effect. Conformal transformation: analytic functions, singularities, Cauchy- Riemann equations, complex potential, application of conformal transformation to some flow cases, Joukowski’s hypothesis, lift of an infinite aerofoil, Theorems of Green, Stokes, Cauchy and Blasius and their application to some hydrodynamic problems. Flow of a real fluid: Navier-Stokes equations, displacement, momentum and energy thickness of the boundary layer, and characteristics of flow around a ship hull.
