GEM 341 E Ship Hydrodynamics 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. ________________________ 2015 -16 Ö.

GEM 341 E Ship Hydrodynamics Homeworks: 1) 2) 3) 4) One set of problems (Resistance) Computation of wave resistance by thin-ship theory (team work) Calculation of effective power by statistical methods (teamwork) Propeller drawing Midterm Project: Propeller selection and design Laboratory study: Model testing and extrapolation to full scale (team work) Exams: 2 Midterm Exams (probably 6 th (resistance) and 11 th (propulsion) weeks) 1 Final Visa Requirements: Minimum 70 % attendance Submission of all homeworks, projects and laboratory reports in a timely and correct manner ________________________ 2015 -16 Ö. Gören 7/8

GEM 341 E Ship Hydrodynamics 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). Please check Ninova and your official ITU e-mail boxes regularly for course related announcements. ________________________ 2015 -16 Ö. Gören 8/8
