Abstract

The objective of this new course is to introduce the students to the field ofheat transfer by convection. This heat transport process is intimately tiedto fluid dynamics, meaning that a solid background in this field is necessary.Convection has direct implications in various industries, e.g. microelectronics cooling, thermal shields protection for space shuttles.

Objective

The objective of this new course is to introduce the students to the field of heat transfer by convection. This heat transport process is intimately tied to fluid dynamics, meaning that a solid background in this field is necessary. Convection has direct implications in various industries, e.g. microelectronics cooling, thermal shields protection for space shuttles. See www.ascomp.ch .

Content

An initiation to 'practical' convective heat transfer will be presented during the first class in terms of computational examples: cooling of electronic boards by fans, liquid film cooling of walls, cooling effectiveness in tube heat exchangers, with single phase and two phase flow. The core of the course will be introduced according to the content below. The course covers the following topics: 1 Fundamental Principles o Conservation Laws o Entropy Generation o Scaling Analysis 2 Boundary Layers o Hydraulic and Thermal Boundary Layers o Integral Solutions o Similarity Solutions 3 Forced Convection o Entrance Length Flow o Fully Developed Flow o Hydraulic Diameter and Pressure Drop o Heat Transfer to Fully Developed Flow o Heat Transfer to Developing Flow o Turbulent Pipe Flow 4 Natural Convection o Laminar Boundary Layer o Integral Solution o Similarity Solution o Vertical Channel Flow o Combined Natural and Forced Convection

Mode
written 120 minutes
Aids
Summary of the script with up to 8 pages and an electronic calculator. Solutions to the exercises delivered are not allowed.
The examination will be based 30% on the theory fromthe material, and the rest on the homeworks. Similarproblems to the homeworks will need to be solved (3 to 4exercises).CFD problems are not concerned. But the finalgrade/mark will depend on what the studentsdid in the Uebungen and CFD.
