# 151-1633-00L  Energy Conversion

 Semester Herbstsemester 2018 Dozierende I. Karlin, G. Sansavini Periodizität jährlich wiederkehrende Veranstaltung Lehrsprache Englisch Kommentar This course is intended for students outside of D-MAVT.

 Kurzbeschreibung This course is tailored to provide the students with a common introduction on thermodynamics and heat transfer. Students can gain a basic understanding of energy, energy interactions, and various mechanisms of heat transfer as well as their linkage to energy conversion technologies. Lernziel Students will be able analyze and evaluate energy conversion and heat exchange processes from the thermodynamic perspective. 1. They will be able to describe a thermodynamic system and its state in the using phase diagrams for pure substances and to apply the first law of thermodynamics, energy balances, and mechanisms of energy transfer to or from a system. 2. Students will be able to describe processes/changes of state in the phase diagrams and evaluate start and end states and the exchange of heat and power in the process.3. They will be able to introduce and apply the entropy and exergy balance to closed and open systems. 4. They will be able to apply the second law of thermodynamics to power cycles and processes, and determine the expressions for the thermal efficiencies and coefficients of performance for heat engines, heat pumps, and refrigerators. They will be able to evaluate the thermodynamic performance of cycles using phase diagrams and critically analyze the different parts of cycles and propose improvements to their efficiency.5. Students will be able to apply energy balances to reacting systems for both steady-flow control volumes and fixed mass systems.6. At the end of the course, they will be able to apply the basic mechanisms of heat transfer (conduction, convection, and radiation), and Fourier's law of heat conduction, Newton's law of cooling, and the Stefan–Boltzmann law of radiation. Finally, students will be able to solve various heat transfer problems encountered in practice. Inhalt 1. Thermodynamic systems, states and state variables2.
