On a Radial Flow Porous Plug and Calorimeter

An experimental study on hydraulic behavior of free-surface radial flow in coarse-grained porous media

The equations of fluids in porous media are very useful in designing the rockfill and diversion dams, gabions, breakwaters and ground water reserves. Researches have been showed that the Forchheimer equation is not sufficient for the analysis of hydraulic behavior of free-surface radial flows; because, in these flows, in addition to the hydraulic gradient and velocity, the variable of radius is...

Expected Performance of the CDF Plug Upgrade Calorimeter at TeV33

We have evaluated the performance of the CDF plug tile/fiber calorimeter under the radiation environment at a luminosity of 1 1033 cm 2s 1 at TeV33. The issues covered are the radiation damage, the anode current of photomultipliers, and the energy miss-measurement due to the minimum bias event pile-ups. The plug calorimeter is expected to perform as precision calorimetry in the pseudorapidity r...

Hydrodynamic stability of flow between rotating porous cylinders with radial and axial flow

A linear stability analysis was carried out for axial flow between a rotating porous inner cylinder and a concentric, stationary, porous outer cylinder when radial flow is present for several radius ratios. The radial Reynolds number, based on the radial velocity at the inner cylinder and the inner radius, was varied from 215 to 15, and the axial Reynolds number based on the mean axial velocity...

A numerical approach on Hiemenz flow problem using radial basis functions

Analytical and numerical investigation of heat and mass transfer effects on magnetohydrodynamic natural convective flow past a vertical porous plate

The aim of this investigation is to study the effect of hall current on an unsteady natural convective flow of a viscous, incompressible, electrically conducting optically thick radiating fluid past a vertical porous plate in the presence of a uniform transverse magnetic field. The Rosseland diffusion approximation is used to describe the radiative heat flux in the energy equation. Analytical a...
