Investigation of the Diurnal Variation of Marine Boundary Layer Cloud Microphysical Properties at the Azores
Publisher: American Meteorological Society
Abstract: new method has been developed to retrieve the nighttime marine boundary layer (MBL) cloud microphysical properties, which provides a complete 19-month dataset to investigate the diurnal variation of MBL cloud microphysical ...
A Climatology of Marine Boundary Layer Cloud and Drizzle Properties derived from Ground-based Observations over the Azores
Publisher: American Meteorological Society
Abstract: In this study, more than four years of ground-based observations and retrievals were collected and analyzed to investigate the seasonal and diurnal variations of single-layered MBL (with three subsets: non-drizzling, virga ...
Study on the Four-Quadrant Homologous Characteristic and Two-Phase Flow Head Degradation of a Reactor Coolant Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the four-quadrant homologous characteristic and analyzes the gas–liquid two-phase flow head degradation of ACP100 reactor coolant pump. The theoretical basis and the operating conditions of the pump's ...
Comparison Analysis on the Hydraulic Performance and Flow Characteristics on a Reactor Coolant Pump Under Rated Operating Condition Between Lead–Bismuth Eutectic and Water Mediums
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Advanced Generation IV nuclear reactors aim to enhance the sustainability, passive safety, reliability, and economic efficiency of reactor operations. Within that, the reactor coolant pump is a critical component in the ...
Effect of Trailing Edge Modification of a Mixed Flow Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern pumps are designed to guarantee a sufficiently large operating range or to satisfy the performance requirements relative to more than one operating point. This study applies trailingedge (TE) modification method ...
Transient Characteristics of a Closed Loop Pipe System During Pump Stopping Periods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to study the transient characteristics of a closedloop pipe system with room temperature water, experiments were carried out based on different pump stopping periods from rate rotational speed to zero. Various ...
Impact of Institutional Pressures on Organizational Citizenship Behaviors for the Environment: Evidence from Megaprojects
Publisher: American Society of Civil Engineers
Abstract: A brisk building boom of megaprojects leads to a wide range of environmental problems, particularly in developing countries such as China. To prevent environmental problems effectively, megaprojects require proactive ...
Optimization of Nonlinear Pressure-Flow Characteristics of a Spring-Loaded Pressure Relief Valve Based on Computational Fluid Dynamics Simulation
