Experimental Study of Multi-phase Flow Hydrodynamics in Stirring Tanks
… tanks in phase separation where multiphase flow is involved. Flotation refers to the process in which air bubbles selectively pick up hydrophobic particles and separate them from hydrophilic solids. This technology is used throughout the mining industry as well as the chemical and petroleum …

Experimental investigation of local properties in two-phase fluid-flow hydrodynamics
… passage frequency were made in a concurrent-flow, vertical rectangular channel (15.0 x 1.25 cm) having an aspect ratio of 12:1. Twenty (20) flows were analyzed with superficial gas and liquid velocities ranging from 0.04 to 0.40 m/s and 0.41 to 0.65 m/s, respectively; A dual-tipped …

Methodological Developments for an Improved Evaluation of Climate Change Impact on Flow Hydrodynamics in Estuaries
The knowledge of flow hydrodynamics within the next decades is of particular importance in many practical applications. In this study, a methodological improvement has been made to the evaluation of the flow hydrodynamics under climate change. This research, indeed, proposes an approach which …

Consequences of spontaneous and anomalous symmetry breaking for the orbital and mass flow hydrodynamics of helium-3
… address three problems associated with the mass flow and orbital hydrodynamics of $\sp3$He-A. The first concerns the form of the T = 0 mass current in local equilibrium; the second is a paradox associated with the non-conservation of superfluid linear momentum at T = 0; and the third involves a …

Heterogeneous flow structure and gas-solid transport of riser
… mechanisms of gas-solid transport and riser flow, investigate heterogeneous flow structures of gas-solid transport and their formation mechanism of the in riser flows, both in axial and radial directions. It provides sound interpretation for the experimental observation and valuable …

Modeling of non-uniform hydrodynamics and catalytic reaction in a solids-laden riser
… This is why, the local coupling between hydrodynamics and reaction kinetics is critical to the development of riser reaction models. The local gas-solids flow structure in riser reactors is highly heterogeneous both in axial and radial direction with back-mixing of catalyst. The radial …

Rain Induced Runoff Simulation Using A 2D Numerical Model
… CCHE2D, a numerical model for free surface flow hydrodynamics, is applied to study the rain induced runoff and channel flow mixed problems. The main goal of this study is to incorporate rainfall as an input into the existing free surface flow model, CCHE2D; to verify and validate the CCHE2D …

Coastal Overwash: Processes and Modelling
Overwash is the flow of water and sediment over the crest of a beach system when the runup level of waves or the water level, often enhanced by storm surge, exceeds the local beach or dune crest height. The impacts of overwash on coastal barriers or low lying mainland coasts are striking. Overwash …

Lagrangian Mechanics Modeling of Free Surface-Affected Marine Craft
… been restricted by the complex nature of the hydrodynamics. The principal challenge is that the vehicle motion is coupled to the ambient fluid motion, effectively requiring one to solve an infinite dimensional set of equations to predict the hydrodynamic forces and moments acting on a marine …

Experimental characterisation of bubbly flow using MRI
… (MRI) towards the characterisation of bubbly flow systems. The principle goal of this study is to provide a hydrodynamic characterisation of a model bubble column using drift-flux analysis by supplying experimental closure for those parameters which are considered difficult to measure by …
