Due to pandemy all educational activities (classes, exams) will be done online.
Course material (syllabus, lecture notes, problems etc.) will be placed on blackboard (bB).
Lecture hours: Thursday 9:00-12:50
Textbook:
Incropera, F.ve P. DeWitt Fundamentals of Heat and Mass Transfer,,Wiley,1996.
Other books that may be used:
Çengel, Y.  Heat Transfer: A Practical Approach,McGraw-Hill, 1998
There are many other boooks on fundamental heat transfer in the library.
Course outline:
Oct. 8   Introduction. Example. Modes of heat transfer. Examples.

Oct. 29   Cumhuriyet Bayramı ( National Holliday) No classes.
Nov. 5   Heat conduction under transient conditions, numerical methods. Mid Term Exam 1, 11:30- 13:00.
Nov. 12   Fundamental concepts and equation of convection. Velocity and thermal boundary layers.
Nov. 19   Convection on external surfaces.
Nov. 26   Convection in internal flow (pipes and channels).
Dec. 3   Natural convection.
Dec. 10   Mid Term Exam 2, 9:00- 11:15.    Problem session, 11:30 -13:00
Dec. 17   Introduction to thermal radiation. Black body radiation. Stefan-Boltzmann law.
Dec. 24   Solar and terrestrial radiation. Emissivity, absorptivity and reflectivity of surfaces. Kirchoff law.
Dec. 31   Radiation heat transfer between surfaces, shape or view factor.
Jan. 7   Methods for calculating radiatiave heat exchange between black and gray surfaces.

Course evaluation: 5 pop-up exams (15%), 2 midterm exams (20 + 20 = %40), Final exam (%45).
All topics covered during the course will be asked in the final exam.
Notes: 10 problem sets (tutorials) will be posted on "blackboard" during the course. Students are urged to solve
these problems. Solutions of the problems will be placed on "blackboard" several weeks after they are posted.
Detailed marking and discussion of one of the problems in each set will be shared with the student. This will
help student to obtain an idea about how her (his) solutions will be graded in the exam. All exams will be
online. Student will do the exam in the classical manner and send its image to the instructor at the end. Exams
will consist of a classical exam, immediately followed by a multiple choice exam based on the classical exam.
