Course description: Course objectives:
: Introduction to the basic forms of heat transfer (heat conduction, heat convection and radiation heat transfer), and its application on the calculation of heat exchangers. Introduction to combustion processes using the laws of energy and mass conservation only. Introduction to the behaviour of moist air.

Enrolment requirements and required entry competences for the course:
Attended Thermodynamics I

Student responsibilities:
Regular attendance of lectures and exercizes, as well as regular homework completion will be documented in Script Runner

Grading and evaluation of student work over the course of instruction and at a final exam:
Appropriate attendance of classes (meaning both, lectures and exercises) will constitute 20% of the final mark, while the outcome of the oral and written exam will account for the rest (40% + 40%)

Methods of monitoring quality that ensure acquisition of exit competences:
The attandence and the overall student activity during lectures and exercises will be regularly followed, as well as student"s feedback regarding presented topics received in direct studentteacher communication or via email. Students are encouraged to communicate during and outside lecture/exercises hours. the principles of Thermodynamics II are widely applicable in other related fields and of my (our) interest is the student"s capability to apply their knowledge upon successfully

Upon successful completion of the course, students will be able to (learning outcomes):

Know modes of heat transfer and apply this knowledge to design and optimization of specific heat apparatus particularly heat exchangers
Calculate the thermal losses (gains), in order to optimize the heating or cooling systems
Calculate the transient temperature fields in order to determine the rate of cooling or heating
Completely control and manage the work of furnaces in different energyplants
Understand the processes of air conditioning and drying with air as working fluid
