Using the popular Heat Transfer Module from COMSOL, this text is designed to provide models for investigating and analyzing heat transfer applications such as conduction, convection, and radiation, etc. Each model covered in the book shows the mathematical development and the resulting computer model. A companion disc provides the files so models can be run in order to observe real-world behavior of the applications. Companion disc with models is included.
Features:
- Companion disc with models from the book
- Covers models from various disciplines
