This book guides the reader through the process of model creation for heat transfer analysis with the finite element method. Describing thermal imaging experiments that demonstrate how such models can be validated, it presents application examples, such as heating water in a kettle, to basement insulation, a heated seat, molten rock, pipe flow, and an innovative extended surface. A companion disc provides the files so models can be run (using COMSOL or other software) in order to observe real-world behavior of the applications.
