Parameter identification in radial flow

Advances in Water Resources, 1991
Abstract 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.

Newtonian radial entrance flow

AIChE Journal, 2000
AbstractThe laminar flow of a Newtonian fluid is considered through a prototype radial entrance geometry that consists of a circular pipe joined to the bottom plate of a pair of parallel circular plates, a configuration that mimics and idealizes important practical flows. The equations of motion are solved numerically to compute the velocity field as a

Simulation of Flow Distribution in Radial Flow Reactors

Industrial & Engineering Chemistry Research, 2006
Flow 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 surface flows

1999
The present study investigated the radially spreading surface flow that is created when a vertical buoyant jet is discharged in shallow water and surfaces. Experiments were conducted for a series of vertical buoyant jets discharging into a shallow circular tank specially designed to simulate an infinite ambient water body so that downstream control ...

Rotating Flow in Radial Turbomachinery

1990
Abstract : The present study addresses the development and implementation of computational procedures for analysis and prediction of flows in centrifugal impellers. Two approaches have been investigated: (a) solution of the Navier-Stokes equations, and (b) solution of an approximate set of viscous primary/ secondary flow equations by an efficient ...

Computation of radially symmetric shocked flows

Journal of Computational Physics, 1971
Abstract A practical method for computing solutions to partial differential equations with radial symmetry is presented. It consists of the following steps: 1. Consider the problem in Cartesian coordinates but store the data only at lattice points of an appropriate lower dimensional subspace. 2.

Radially symmetric ice sheet flow

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1997
Summary: The evolution equations for a radially symmetric grounded ice sheet flowing under gravity are formulated on the basis that the ice is an incompressible nonlinearly viscous heat conducting fluid with temperature-dependent rate factor. The reduced model, which comprises the leading order balances when longitudinal gradients are small compared ...
