RISTwo-Dimensional Flow Boiling Characteristics With Wettability Surface in Microgap Heat Sink and Heat Transfer Prediction Using Artificial Neural Network
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As technology becomes increasingly miniaturized, thermal management becomes challenging to keep devices away from overheating due to extremely localized heat dissipation. Two-phase cooling or flow boiling in microspaces ...
Numerical Prediction of Maximum Load Carrying Capacity of Cracked Alloy 690TT Steam Generator Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a finite element (FE) simulation technique to predict maximum loadcarrying capacity of cracked steam generator tubes and its application to Alloy 690TT tubes. The simulation method is based on a simplified ...
Inclusion of Linearized Moist Physics in NASA’s Goddard Earth Observing System Data Assimilation Tools
Publisher: American Meteorological Society
Abstract: nclusion of moist physics in the linearized version of a weather forecast model is beneficial in terms of variational data assimilation. Further, it improves the capability of important tools, such as adjoint-based observation ...
Evaluation of the Creep Rupture Behavior of Alloy 690 Steam Generator Tubes Considering the Pressure Ramp Rate
Publisher: The American Society of Mechanical Engineers (ASME)
