Course objectives: At the end of the course, students will
- recognize the presence and importance gas-solid processes of chemical engineering. Some of the fundamentals of these processes will be directly applicable to solid-liquid and liquid-liquid suspensions.
- understand the creation, growth, and transport of small and large particulates.
- be able to apply the fundamentals learned through this course for the development and modification of instrumentation and reactors that process particulate materials.
· There will be two midterm exams and a final exam. Using your notebooks will be allowed during the exams. Books will not be allowed. Any other required material, e.g. supplementary equations, physical parameters, etc., will be provided during the exam. It is your responsibility to understand the exam questions. If you have difficulty with English, you may bring a dictionary with you.
· Please do your best to take the exam during its scheduled time. If you miss an exam with a certified medical excuse, you may take a make-up exam near the end of the semester.
· Per every 1-2 weeks, a problem set will be uploaded to ODTÜClass as homework (a total of 7 is expected). Homework will be submitted as a group. Please form groups of 3. Answers may be posted on ODTÜClass. Feel free to stop by during office hours to get assistance on course materials. You can also schedule an alternative time to meet by email.
· To get an AA in this course, you must attempt and do satisfactory work on all homework in addition to getting the necessary weighted average grade on the exams.
· The weighted average grade will be calculated as: two midterm exams: 2 × 25% + HWs: 15% + final exam: 35%.
· Attendance is mandatory in this course.
