GEM341E Ship Hydrodynamics ________________________________________________ Ö. Gören4/ Learning Objectives: # Understand the physical phenomena around the moving bodies in a fluid with a free surface # Understand the flow conditions in which the propellers operate # Calculate the resistance of ships by means of approximate models (empirical, statistical, computational) # Learn how to make experiments and evaluate the experimental data acquired in a towing tank # Learn the geometry of a conventional propeller and understand the hydrodynamic principles of how a propeller generate thrust and torque # Learn the essentials and details of propeller design # From resistance to propulsion; calculate the required engine power to propel the ship at the design speed.

GEM341E Ship Hydrodynamics ________________________________________________ Ö. Gören6/ Course format: Most of the times there will be lectures and sometimes tutorials aiming at the understanding of the lectures and the given concepts In the tutorials, the students are encouraged to solve the given problems by themselves and to discuss the problems with classmates and with the instructor Requirements and Grading: Individual homeworks should strictly be done individually and submitted to the instructor or teaching assistant in person Teamwork studies should be done with a collaborative manner in which the contribution of all the team members should be equally required

GEM341E Ship Hydrodynamics ________________________________________________ Ö. Gören7/ Homeworks: 1)One set of problems (Resistance) 2)Computation of wave resistance by thin-ship theory (team work) 3)Calculation of effective power by statistical methods (teamwork) 4)Propeller drawing Midterm Project: Propeller selection and design Laboratory study: Model testing and extrapolation to full scale (team work) Exams: 2 Midterm Exams (probably 6th (resistance) and 11th (propulsion) weeks) 1 Final Visa Requirements: Minimum 70 % attendance Submission of all homeworks, projects and laboratory reports in a timely and correct manner

GEM341E Ship Hydrodynamics ________________________________________________ Ö. Gören8/ Grading: Homeworks: 15 %, Midterm project: 10 %, Laboratory: 5 %, Midterm exams: 25 %, Final Exam: 45 % The grading system will be based on a (relative) normal curve distribution in the peer group. But in any case, students can’t get DD or higher marks unless their overall grades are 40/100 or higher. Course Material: There are no official text book, but a couple of text books recommended to be studied as reference material Lecture notes (Resistance) can be found on Ninova (website).
