Original study plan 
Bachelor's programme Sustainable Polymer Engineering & Circular Economy 2023W 
Objectives 
Students will be able to:
 explain the heat transfer phenomena occurring in a simple solar collector,
 relate typical thermal properties of plastics to other materials,
 reproduce the most important thermodynamic ratios and be able to estimate them for given data without electronic help, as well as
 analyze practical problems from solar thermal energy, building physics, or plastics technology, select the simple or coupled heat transfer cases that correctly describe them, simplify them for the specific problem, and calculate them using a calculator under given boundary conditions.
Students have improved selfmanagement as well as strengthened analytical and calculation skills.

Subject 
Introduction to the physical principles of heat transfer and analytical modeling of heat transfer processes. Basic concepts and methods of heat transfer: Key figures and their ranges, thermal radiation, steadystate heat conduction and heat transfer, transient heat conduction, convective heat transfer, heat exchangers. Case studies from solar thermal energy, plastics technology and building physics. Deepening of the calculation competence by means of analytical calculations of practical application cases.

Criteria for evaluation 
Written or oral examination after the end of the course, after which 3 examination dates will be offered per semester. 40% of the grade is defined by participation and passing short tests during the course.

Methods 
Flipped Classroom: Students learn the theoretical basics in selfstudy (supported by videos, texts, script) before the respective meeting in the lecture hall. In the lecture hall, the practical significance is discussed using examples from solar thermal and plastics technology, and the practical application is deepened using calculation exercises.
