This book represents a collection of the favorite experiments in heat transfer and thermodynamics of some of the world's eminent scholars in the field. It was my intent to include experiments that they had used in their lectures which had a proven track record in regard to students' reaction and understanding. Experiments that were too complicated, even bordering on research, or too esoteric were rejected.

Some of the experiments are well known, some of them are relatively new; and for all of them I have tried to devise the presentation that appears to be best from a consistent point of view. The book has been prepared as a connected account; each experiment is intended to be used as a whole rather than in parts. The readers were envisioned as both engineering and physics students; however, the appeal will probably lie with engineering students from all disciplines.

A brief word is necessary about the selection of topics to be found in this book as well as the order in which they were placed. The experiments selected were varied, representative, new, old, fascinating, and challenging. I selected those I thought my students would enjoy as well as students in Japan, Germany, Brazil, and other countries with different backgrounds and methodologies.
