RISCompromise Orifice Geometry to Minimize Pressure Drop
Publisher: American Society of Civil Engineers
Abstract: A compromise orifice geometry is experimentally proven to cause a smaller local pressure drop in conduit flow. An orifice installed as an energy dissipator in a flood conduit is required to dissipate a designed amount of ...
Current Crowding and its Effects on Electromigration and Interfacial Reaction in Lead-Free Solder Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current density distribution in a line-to-bump structure as a function of cross-sectional area ratio of the electrical conductor was investigated, as well as the effects of current crowding ...
Investigation on the Contribution of Large-Scale Fluctuation and Small-Scale Disturbance of Coolant to Heat Transfer Enhancement in a Rectangular Channel With Pin Fins
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow field in a channel with staggered pin-fin array was measured using time-resolved Particle Imaging Velocimetry (PIV). The distributions of flow field statistics were compared with those of Nusselt number on the ...
Investigation on the Flow and Heat Transfer Characteristics in a Multi-Pass Channel Using Magnetic Resonance Velocimetry and Transient Thermochromic Liquid Crystal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The three-dimensional flow field in multi-pass channels with and without ribs was measured by magnetic resonance velocimetry (MRV), while heat transfer performance on the endwall of channels in the same geometry was ...
Arctic Oscillation during the Mid-Holocene and Last Glacial Maximum from PMIP2 Coupled Model Simulations
Publisher: American Meteorological Society
Abstract: Changes in the Arctic Oscillation (AO) during the mid-Holocene and the Last Glacial Maximum were compared to preindustrial (PI) simulations using four coupled ocean?atmosphere models [i.e., Community Climate System Model ...
The Shallowing Surface Temperature Inversions in the Arctic

Investigation on Flow Characteristics and Its Effect on Heat Transfer Enhancement in a Wide Channel With Staggered Diamond-S Pin Fins
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow statistic in the mid-plane of a rectangular channel with diamond-s pin fins was obtained by means of particle imaging velocimetry at Re = 10,000. Large-scale and small-scale fluctuations were separated using proper ...
Numerical Simulation and Assessment of the Effects of Operation and Baffling on a Potable Water Service Reservoir
Publisher: American Society of Civil Engineers
Abstract: A major water-quality concern in a potable water service reservoir is the potential loss of chlorine residual, which is closely related to the flow pattern. In this article, the effects of operation and baffling on the ...
Effects of Baffle Configurations on the Performance of a Potable Water Service Reservoir
Publisher: American Society of Civil Engineers
Abstract: Because a baffle is a device used for altering the flow pattern in a tank, the use of a baffle wall was considered to modify an existing potable water service reservoir operating as a storage tank to achieve better water ...
Passive and Active Methods for Enhancing Water Quality of Service Reservoir
Publisher: American Society of Civil Engineers
Abstract: Knowledge of flow pattern and water age distributions in service reservoirs is of the utmost importance for ensuring water quality supplied to the customers. In this article, a balancing reservoir was first investigated ...
