Probabilistic Flow Regime Map Modeling of Two -Phase Flow
… tubes using a common probabilistic two-phase flow regime basis. Probabilistic two-phase flow maps are experimentally developed for R134a at 25°C, 35°C, and 50°C, R410A at 25°C, mass fluxes from 100 to 600 kg/m2-s, qualities from 0 to 1 in 8.00 mm, 5.43 mm, 3.90 mm, and 1.74 mm …

Understanding links between flow regime and fish populations in the Saskatchewan River Delta
… ability to harvest adult fish. In rivers, the flow regime dictates water depths and velocities that subsequently trigger spawning and enable the survival of juveniles. However, anthropogenic activities such as the operation of hydroelectric generating stations can change the natural hydrograph …

EFFECTS OF FLOW REGIME ON FISHES AND FISHERIES: FROM LIFE HISTORIES TO ECOSYSTEM SERVICES
Stream flow in freshwaters is considered a “master variable” influencing processes and traits from individual organisms to ecosystems. Due to this strong linkage, anthropogenic modification of flow regimes in freshwater ecosystems worldwide continues to have major impacts on populations, species, …

Impacts of Stormwater Management Practices and Climate Change on Flow Regime and Channel Stability
… were short in duration, with the greatest peak flows resulting from storm events with durations less than 24 hours. However, results indicated that despite the use of multiple SCMs, channel changes, including both degradation and aggradation up to 1.2 m, are likely over a period of 16 years. …

The Flow Regime of Function: Influence of flow changes on biogeochemical processes in streams
… disturbances within a stream is elevated flow. Elevated flow can both stimulate ecosystem processes and impede them. Consequently, flow plays a critical role in shifting the dominant stream function between biological transformation and physical transportation of materials. To garner …

Environmental Flow Regime Recommendations for the Promotion of Salicaceae Seedling Recruitment in California’s Central Valley
… are being degraded due to alteration of natural flow regimes caused by the creation of dams and diversions to serve human needs for water. Alteration to natural flow regime affects a river’s flow magnitude, frequency, duration, timing, and rate of change of flow. These changes have major …

Two-Phase Pressure Drop and Flow Regime of Refrigerants and Refrigerant -Oil Mixtures in Small Channels
… in their design, more exact understanding of the flow inside them is necessary. A decrease in diameter enhances the heat transfer (which takes place at the inner walls of the tubes), but also increases the pressure drop (as the diameter decreases, it becomes like drinking a milkshake through a …

Modeling the Impacts of Land Use Activities on the Subsurface Flow Regime of the Upper Roanoke River Watershed
… impact of land use activities on the subsurface flow regime in the Upper Roanoke River Watershed in Virginia to determine the impacts of land use change on the subsurface flow system, and to provide a tool for future management decisions. Land use activities can impact the groundwater system in …

Mass transfer from spherical gas bubbles and liquid droplets moving through power-law fluids in the laminar flow regime
… type continuous phase in to so-called creeping-flow region. The Nakano and Tien stream functions allow the Sherwood number to be determined as a function of the Peclet number, power-law index, and a viscosity ratio parameter. The Hirose and Moo-Young relation is shown to be a limiting case of …

Non-intrusive two-phase flow regime identification and transport characterization in microchannels subject to uniform and non-uniform heat input
… a uniform heat sink temperature. Under two-phase flow conditions, the heat transfer and pressure drop are a function of the local flow regime. Development of sensors that detect local void fraction and flow regimes may enable better understanding of the fundamental flow phenomena. ^ The void …

THE INFLUENCE OF SEASON, FLOW REGIME, AND WATERSHED LAND USE AND LAND COVER ON NUTRIENT DELIVERY TO TWO RAPIDLY URBANIZING WATERSHEDS IN CENTRAL INDIANA, USA
… quality vary seasonally and with respect to flow regime, that urbanization may result in decreased nitrate input, and that phosphate and dissolved organic carbon concentrations will likely remain constant as the watershed is developed. Results also indicate that riparian buffer downstream of …

The effects of low aspect ratio and heat exchanging internals on the bubble properties and flow regime in a pilot-plant bubble/slurry bubble column for Fischer-Tropsch synthesis
… enough height to established the fully developed flow regime. As a result of the variation in the bubble properties that in turn reflected on the flow regime transition, therefore, the presence of internals and decreasing the aspect ratio delay the transition from the transition flow regime to …
