RISA Mechanistic Model for Predicting Pressure Drop in Vertical Upward Two-Phase Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A comprehensive mechanistic model is formulated to predict flow patterns, pressure drop, and liquid holdup in vertical upward two-phase flow. The model identifies five flow patterns: bubble, ...
Basis and Development of Toughness Requirements for Class 2, Class 3, Containment and Component Support Materials in Section III of the ASME Code
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In 1972, Section III of the ASME Boiler and Pressure Vessel Code adopted new fracture toughness requirements for Class 1 components based on fracture mechanics concepts. In the ensuing several ...
Fracture Toughness Requirements for ASME Section VIII Vessels for Temperatures Colder Than 77K
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Earlier research work conducted at MIT and NIST indicated that CVN specimens with an initial temperature at or near 4K (−452°F) actually fracture at temperatures significantly above 4K due ...
