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

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 ...

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 ...

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.

Parameter identification in radial flow
Advances in Water Resources, 1991Abstract The classical inverse parameter identification problem is solved using an indirect method. This method is based on the minimization of an objective function or error criterion consisting of three parts: 1) least-squares error of head residuals; 2) prior information of flow parameters; and 3) regularization.
