Generalized Radial Flow in Synthetic Flow Systems
Groundwater, 2012Traditional analysis methods used to determine hydraulic properties from pumping tests work well in many porous media aquifers, but they often do not work in heterogeneous and fractured‐rock aquifers, producing non‐plausible and erroneous results. The generalized radial flow model developed by Barker (1988) can reveal information about heterogeneity ...

A theory for radial jet reattachment flow
1st National Fluid Dynamics Conference, 1988Both laminar and turbulent flows are considered. A component analysis is used for the theoretical treatment. The jet flow component is modeled with Schlichting's velocity profile for the laminar case and with Gortler's velocity profile for the turbulence case. The influence of the nozzle exit geometry and the spacing between the radial jet and the flat

We determine the radial component of the supergranular flow velocity by examining the center-to-limb variation of the Doppler velocity signal. We acquire individual Doppler images obtained with the MDI instrument on the SOHO spacecraft and process them to remove the p-mode oscillation signal, the axisymmetric flows, the convective blueshift signal, and

Abstract The radial flow of a non-Newtonian liquid between parallel plates has been theoretically examined for a Rivlin-Ericksen fluid. It was found that by experimentally measuring the radial pressure distribution and comparing the data with theoretical predictions, both the lower-limiting viscosity and a normal stress coefficient of the fluid may ...

Throughout the history of turbocharging, the type of compressors and turbines used have reflected the general state of the art, at any particular time, in the field of turbomachinery. The very first turbochargers (chapter 2) were built with radial flow single or two-stage compressors, incorporating backswept vaned shrouded impellers (figure 3.1a ...

Amplitude Blowup in Radial Isentropic Euler Flow
SIAM Journal on Applied Mathematics, 2020The authors consider inviscid isentropic flow described by the compressible Euler system in 2 or 3 spatial dimensions. An additional assumption of symmetry is made: velocity is radial, and all variables depend on the distance to the origin. The aim is to prove the possibility of unbounded solutions due to wave focusing possible in several spatial ...

There are two basic types of turbine suitable and used at present in turbochargers, the radial flow and the axial flow. The radial flow turbine is mainly used for small automotive or truck turbochargers; the axial type is commonly used for the large turbochargers applied to medium-speed stationary and railway traction engines and large marine engines.

Simulation of Flow Distribution in Radial Flow Reactors
Industrial & Engineering Chemistry Research, 2006Flow distribution in four possible configurations, CP-z, CP-π, CF-z, and CF-π, of a radial flow reactor is investigated using computational fluid dynamics (CFD). The CFD models are validated using published experimental data. It is found that one of the π-flow configurations always has the most uniform flow distribution.

Radially spreading buoyant flows
Journal of Hydraulic Research, 2001The nature of the radially spreading flow that forms after a vertical buoyant jet impinges on the surface has been investigated. Previous studies have provided conflicting conclusions as to whether or not an internal hydraulic jump forms in the radially spreading flow.
