This monograph comprehensively describes phenomena of heat flow during phase change as well as the dynamics of liquid solidification, i.e. the development of a solidified layer. The book provides the reader with basic knowledge for practical designs, as well as with equations which describe processes of energy transformation. The target audience primarily comprises researchers and experts in the field of heat flow, but the book may also be beneficial for both practicing engineers and graduate students.

Zygmunt Lipnicki is Profesor of the Institute of Environmental Engineering at Zielona Góra University in Poland. He received his doctoral degree in 1985 at Poznä Technical University, and he received his habilitation degree from Poznä Technical University in 2000. Dr. Lipnicki¿s teaching focuses primarily on fluid dynamics, thermodynamics and heat transfer. His current research programs include analytical and experimental studies of thermal resistance of contact layer in solidification process.
