In the condensation section, the condensate and the vapor have a heterogeneous flow, which is characterized by intensive turbulence. Notes on twophase flow, boiling heat transfer, and. Mostafa ghiaasiaan providing a comprehensive introduction to the fundamentals and applications of flow and heat transfer in conventional and miniature systems, this fully enhanced and updated edition covers all the topics essential for graduate courses on twophase flow, boiling, and condensation. This book is the outcome of more than fifteen years of teaching graduate courses on nuclear reactor thermalhydraulics and twophase flow, boiling, and condensation to mechanical, and nuclear.

At the beginning of the condensation section, the flow pattern is annular, because in the core the velocity of the vapor is much higher than the velocity of the liquid. Flow boiling heat transfer and twophase flow of carbon. In horizontal flow, in addition to the above flow regimes, there can also be stratified flow, typical of low flow rates at which the two phases separate under the effect of gravity. This text is an introduction to gasliquid twophase flow, boiling and condensation for graduate students, professionals, and researchers in mechanical, nuclear, and chemical engineering.
