Planned Learning Activities and Teaching Methods

The learning and teaching methods are class-based lectures and tutorial sessions, and coding in the computer labs. Entire semester the courses will be delivered at the computer lab. All steps from transfering the physical problems into the mathematical models and analysing the models with computer-aided approaches will be discussed with the students.

Assessment Criteria

The assessing criteria involve one mid-term exam, several assignments, presentations, and a final exam. The mid-term and final exams will be computer-based in a laboratory. Students will transfer some physical problems to mathematical models in the midterm and final exams. At first, heat transfer calculations will be carried out to evaluate spatial and temporal temperature variations. Then, the thermodynamic-based energy, entropy, and exergy analyses will be conducted for several design parameters, and the results will be discussed. The codes will be developed in MATLAB software. The models will be reported on paper, and the codes and results will be reported on a computer. The students will upload all exam materials to a system that will be announced by the lecturer. Homeworks and presentations would also be on developing computer codes to resolve physical problems involving thermal energy storage. Homeworks and presentations would be prepared either induvial or with team members. The lecturer will define the aims, scope, and deadline of a homework during the semester.

Language of Instruction

Turkish

Course Policies and Rules

The courses will be taught in the computer laboratory to build the theoretical foundations and computer-aided analysis skills. Homeworks will be assigned to students every bi-weekly, and students should present the results after completing the tasks. It is expected that students will regularly attend all lectures throughout the semester.
