Flow regime identification in fluidized beds by analysing pressure fluctuations signal based on kolomogrov entropy approch

, 2016
The investigation of flow regime in gas-solid fluidized bed reactors is very important for their design and scale-up as well as effective operation. In addition, the degrees of mixing, mass and heat transfer in these reactors depending strongly on the ...

Local flow regime analysis in vertical co-current downward two-phase flow

, 2013
In this work, both global and local flow regimes in two-phase downward flow in a 50.8 mm internal diameter pipe in adiabatic conditions have been identified.

Performance Analysis and Flow Regime Identification of Fractured Horizontal Wells in Tight Oil Reservoirs

, 2017
Fractured horizontal wells are widely used to produce tight oil. But different fracture patterns could be generated in different reservoirs, which results in different well performances.

Two-phase flow meter for determining water and solids volumetric flow rate in vertical and inclined solids-in-water flows

Multiphase flow can be defined as the simultaneous flow of a stream of two or more phases. Solids-in-water flow is a multiphase flows where solids and liquid are both present. Due to the density differences of the two phases, the results for such flow is

Monitoring sand particle concentration in multiphase flow using acoustic emission technology [PDF]

, 2014
Multiphase flow is the simultaneous flow of two or several phases through a system such as a pipe. This common phenomenon can be found in the petroleum and chemical engineering industrial fields.

Mechanism of Fish Habitat Selection Based on Hydrodynamic Indicators Under Multiple Topographic Conditions for Ecological Restoration Requirements

Ecology and Evolution
The establishment of hydropower projects has altered the flow regime and structure of fish habitats. Various habitat restoration measures based on natural river morphology have been implemented, but the effects of habitat restoration and the hydrodynamic
