COURSE OBJECTIVES
To provide training of mechanical engineers to
understand the unique characteristics of
the ocean environment, local and global scale, and
to provide background on engineering and design tools
that are commonly used by engineers working with
system and component designs of ocean - ship systems.
DESIRED COURSE OUTCOMES
At the end of the course, the students should
understand general scientific properties that
characterize the main body of the oceans;
comprehend mechanisms such as Coriolis force that
drive large-scale ocean currents;
understand components of drags that contribute
to the resistance of a marine vehicle and
the associated engineering skills in model-testing
that quantify the drag characteristics of a ship hull;
comprehend simple harmonic surface-wave theory,
with strong realization of the underlying
concepts of wave kinematics, wave energy, and group velocity.
TOPICS COVERED
Physical properties of the oceans, overall
characteristics, ocean circulation, atmospheric interaction;
global heat balance, water balance and salt balance;
wind-generated surface-waves;
surface-wave dynamics, equations of motion, wave energy;
random processes, random wave description, spectral description;
design considerations of ocean systems;
fluid-dynamic drag; unsteady forces, dimensional analysis;
principles of model testing, calm-water performance;
linear system theory for motion prediction; response operators;
equations of motions for ocean systems; wave excitation;
response analysis in frequency domain;
nonlinear forces and nonlinear motion dynamics.
CLASS/LABORATORY SCHEDULE
Three hours of lectures and 1 hour of discussion section.
One week of laboratory experiments totaling about ten hours of work during the week
CONTRIBUTION OF THE COURSE TO MEETING THE
PROFESSIONAL COMPONENT
Students will be exposed to issues, terminology, and design practice of the sector of maritime affairs and maritime engineering of the US and the rest of the world. Mechanical Engineers often find themselves working on the design of mechanical systems that operate in the ocean environment, which include ship-board machinery, navigation & control systems, underwater robotics, and propulsion devices, to name a few.
RELATIONSHIP OF THE COURSE TO ABET PROGRAM OUTCOMES
An ability to apply knowledge of mathematics, science, and engineering
An ability to design and conduct experiments, as well as to analyze and
interpret data.
An ability to design a system, component, or process
to meet desired needs within realistic constraints
such as economic, environmental, social, political,
ethical, health and safety, manufacturability, and sustainability.
The broad education necessary to understand the impact of
engineering solutions in a global, economic, environmental,
and societal context.
An ability to use the techniques, skills, and modern
engineering tools necessary for engineering practice.
ASSESSMENT OF STUDENT PROGRESS TOWARD COURSE OBJECTIVES
Six sets of homework problems with two sets
involved with design issues of the topics being addressed.
One laboratory report from each team of four to five students.
One midterm exam
and a final exam.
