They focus, in particular, on the influence of the flow regime and on the effects of the geometrical properties.
The agreed method means CEWH entitlements can influence a flow regime in the lower Darling without affecting overall water security," Mr Reynolds said.
All the cases in the simulation were based on the turbulent flow regime, as all the test points in the physical experiment calibration were in the turbulent flow regime.
The knowledge of the flow regime of the liquid phase is fundamental to dimension the treatment unities, because the way the fluid flows inside them may influence the velocity of the biological reactions, through changes on the mass transfer rate and on the reactions distribution along the reactor.
1, adapted from Souza & Botrel (2004), is valid for microtubes operating in the laminar flow regime and contains terms that allow to quantify the head loss distributed along the microtube, the local loss resulting from the narrowing of the flow lines at the microtube inlet hole, the kinetic head on the discharge end of the microtube and the vertical distance between the microtube discharge hole and the lateral line.
1): stable flow (1), sharkskin instability (2,3), stick-slip (4), second stable flow regime or superextrusion (5), and gross melt fracture (6).
This flow regime can be further classified into impact zone also termed as strongly non-linear zone and transition zone or weakly non-linear zone.
The arrangement of the phases in a gas-liquid pipe flow, known as the flow regime, depends on variables such as the flow rates of the separate phases, the pipe diameter, and the phase densities.
Numerous experimental investigation have been carried out by researchers on different types of pipes or tubes using nanofluids under turbulent flow regime using nanofluid with single phase approach.
Heat transfer in laminar fluid flow regime in pipes (Re [less than or equal to] 2300).
Advanced hydrodynamics and improved efficiency have been combined to give an excellent flow regime, which produces the cleanest cut trench possible by a mass or controlled flow excavator.
The values for minimum discharge commonly lie between 20% and 30% (Table 2), but are anomalously small for the Great Bear River, which receives outflow from Great Bear Lake, and for the Mackenzie River at Norman Wells, where inflows from most tributaries of the basin have coalesced to produce an integrated nival flow regime with small inter-annual deviance in its summer minimum discharge.
