Sabanci University Faculty of Engineering and Natural Sciences ME309 Heat and Mass Transfer Course Information, 2008-2009 Spring Term Credit and Content ME309 is a 3-credit course for the third year and higher classes in the Faculty of Engineering and Natural Sciences. ME307 Fluid Dynamics is a pre-requisite for the course, which can be waived for candidates who are proficient in linear algebra and differential equations. Current mechatronic systems involve electro-mechanical, thermo-fluidic and even electro-chemical components. Heat & Mass Transfer course is intended to help undergraduates at the FENS (also some graduates) to have knowledge and skills to design thermal components in complex systems drawn from manufacturing, electronics, consumer products, and energy systems. Topics covered in the course are: transient and steady heat conduction in single and multi-dimensions, forced and natural convection, boiling and condensation, radiation and mass transfer. Emphasis will be on the heat transfer and mass transfer will be covered with analogies to heat transfer. Classes Lectures: Mondays 9:40-11:30; Wednesdays 8:40-9:30 Lecturer: Serhat Yeşilyurt, Rm. 1052, x9579, syesilyurt@sabanciuniv.edu.

Any attempt of cheating and copying of solutions from any source will result in the reduction 1 of homework grade to zero or disciplinary action. If cheating in homework becomes systematic throughout the class, homework’s contribution will be removed from the calculation of the final grades. Lectures (Tentative schedule) Wk 1. Introduction.

Those who need additional problem solution sessions may ask for additional recitation hours and seek for additional tutoring from the instructor and TA on office hours. 2
