Two-Phase Flow, Boiling, and Condensation S. 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 two-phase flow, boiling, and condensation. BOILING MAPS Vertical up flow, preferred configuration for boiling channels As buoyancy helps mixture flow & slip velocity; improved heat transfer Flow boiling in horizontal, vertical down flow are also of interest Horizontal boiling channels are not uncommon Flow boiling in a vertical, downward configuration occur in accident conditions in PWR.
