Flow through Rigid Vegetation Hydrodynamics
… requires improved knowledge of the detailed flow structure within the vegetation. Instead of spatial averaging, this study uses discrete measurements at multiple locations within the canopy to develop velocity and turbulence intensity profiles and observe the changes in the flow …

Estimating Flow Through Rock Weirs
… coefficients that improve predictions of flow through rock weirs. A flume study was conducted to develop a rock weir equation and discharge coefficients. Scaled model rock weirs were tested in a 1 m x 8 m x 0.4 m recirculating flume. Rock weirs varied by length (0.152 m, 0.305 m, and 0.457 …

Turbulent flow through a rectangular channel
… measurements. It had negligible vibration and flow oscillation. Its length was 200 channel heights, sufficient to produce fully developed turbulent flow. The optical system had a specially designed optical table and traverse; optical glass windows were used as viewing ports.

Multiphase immiscible flow through porous media
… finite element model is developed for multiphase flow through soil involving three immiscible fluids: namely air, water, and an organic fluid. A variational method is employed for the finite element formulation corresponding to the coupled differential equations governing the flow of the three …

Resistance to Flow Through Riprian Wetlands
… The research described in this thesis focuses on flow processes within ecosystems known as riparian wetlands. An attempt has been made to summarize existing research in this field to ensure that a contribution will be made to the field of hydraulics. Included in this thesis are results from …

Flow through and around fish farming nets
… measurements were used to investigate current flow through and around net panels and cages. For the numerical computations a porous media model was used to represent the net allowing efficient computation of both exterior and interior flow fields. The model was calibrated using tow tank …

Periodic cell models of flow through porous media
… problems are analyzed to study the microscopic flow within porous media. In Part 1, the primary focus is on the flow near the surface of a porous body. The idealized system consists of two-dimensional media of infinite and semi-infinite periodic lattices of cylindrical inclusions. The solution …

Shear stresses in turbulent flow through concentric annuli
… wall shear stresses in fully developed turbulent flow in concentric annuli is presented. By means of a specially constructed 6 m test rig known as the 'floating sleeve', results of individual wall shear stresses, friction factors and shear stress distributions were obtained for Reynolds numbers …

Improving ICU patient flow through discrete-event simulation
Massachusetts General Hospital (MGH), the largest hospital in New England and a national leader in care delivery, teaching, and research, operates ten Intensive Care Units (ICUs), including the 20-bed Ellison 4 Surgical Intensive Care Unit (SICU), a versatile unit which has a major role in …

Velocity fluctuations in slow flow through porous media
… study the spatial statistical properties of slow flow through porous media on the pore scale by a combination of numerical simulation and theoretical arguments. I demonstrate that the flow patterns undergo a transition from swirls to strongly focused and channel-like patterns for decreasing …

Flow-Through Electroporation in Asymmetric Curving Microfluidic Channels
… can be delivered into cells continuously. Flow-through electroporation systems can overcome the issue of low sample volume limitation. In addition, in our method, electro-pulsation can be done by using a simple dc power supply, without the need for any extra equipment. Furthermore, our …

Fluid flow through connected sub-seismic features in mudstone
… was studied to investigate the controls on fluid flow through low permeability clastic rock. Turbidite flows are present within the shale as very thin (1-5mm) fine grained sandstone beds, channels and lenses which would not be picked up by wireline logging. The shale is cut by a series of …

Investigation and modeling of unsaturated flow through swelling soils
Although the theory of water movement through an unsaturated, swelling soil has been developing for a number of years, the efficiency of the results has been limited, and the developed models have suffered from a lack of a mechanism to reliably define water flow and experimental techniques for …
