Heat Transfer II

About this course
The course presents a detailed description of conduction, convection and radiation. It is mainly focused on 1-D and 2-D steady state and transient systems. A significant part of the course is dedicated to radiation (properties and radiation exchange between surfaces), view factors and thermal resistance circuits. Heat exchangers and basic storage units theory is also covered as a means for studying and finally selecting appropriate heat exchangers.
Expected learning outcomes
Upon completion of the subject, students will be able to:
a) understand the basic concepts of conduction, convection and radiation. b) perform combined studies of all heat transfer modes in various environments (houses, factories, etc.). c) calculate heat loss from fins of uniform and non-uniform cross section. d) understand the basic concepts of thermal boundary layer and solve complicated thermal resistance circuits (Kirchhoff’s law, view factors, black body radiation etc.). e) study the finally select the appropriate heat exchanger that suits specific and well-defined requirements.
