Efficient Heat Transfer (EHT)5 ECTS
(englische Bezeichnung: Efficient Heat Transfer)
(Prüfungsordnungsmodul: Efficient heat transfer)

Lehrveranstaltungen:

• • Efficient Heat Transfer
    (Vorlesung mit Übung, 5 SWS, Michael Rausch et al., Mo, 9:15 - 11:45, H5; Fr, 8:15 - 9:45, H5)

Empfohlene Voraussetzungen:

To succeed in this course, students will need to apply acquired knowledge from engineering thermodynamics, fluid dynamics, and heat transfer. Skills in engineering thermodynamics form the basis for understanding the concept of exergy that is used to evaluate the efficiency of heat exchangers. As this efficiency depends on both heat transfer performance and hydraulic design, fundamental knowledge on the different mechanisms of heat transfer and on fluid flow is necessary.

Inhalt:

• Thermal and hydraulic design of heat exchangers

• Performance criteria for efficient heat transfer

• Minimization of exergy loss via optimization with respect to pressure loss, temperature gradients, mixing effects and heat loss to the ambience

• Surface design and enhancement devices in single-phase heat transfer

• Optimization of condensation heat transfer by the promotion of dropwise condensation as well as different types of finned tubes

• Enhancement of boiling heat transfer by structured surfaces

• Additives for the enhancement of heat transfer

• Examples for heat exchangers optimized for specific tasks

• Examples for the improvement of process efficiencies by enhancement of heat transfer, e.g., in power plants or in seawater desalination
