RISImprovement of the RELAP5-3D Condensation Heat Transfer Model in the Presence of Noncondensable Gases
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Condensation of steam on the primary side of steam generator in a pressurized water reactor is one of the means of removing decay heat during accident scenarios such as a small break loss of coolant accident. With the ...
Evaluation of Mechanical and Thermomechanical Water Vapor Compression Techniques for Enabling High Temperature Lift Hydration-Based Chemical Heat Pumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Achieving high temperature lifts (>200K) via a chemical heat pump based on salt hydration/dehydration reactions requires the transport of water vapor from low to high pressure. Alternative compression approaches require ...
