Dual-Isotope Spectrometric Gamma Densitometer for Diagnostics of Three-Phase Oil–Water–Gas Flows

نویسندگان

چکیده

The operation of a gamma densitometer (GD) ID = 100 mm is considered; it intended for the diagnostics three-phase oil–water–gas flows using separationless method, when composition components determined by spectrometric analysis irradiation with two different photon energies. 241Am and 137Cs isotopes, installed in same housing, are used as sources, while detector made on basis BGO crystal 40 diameter height. Information about design, measuring electronics, main characteristics GD given. method temperature stabilization recorded radiation intensities both isotopes within range ambient from 10 to 35oC presented.

Gamma Spectrometric Analysis of Iron Ore Samples of Arak, Iran

Introduction Iron ore is one of the most important natural raw materials that is widely used for manufacturing iron and steel. This type of ore contains various amounts of radionuclides; thus, exposing workers handling their extraction, transportation, and processing to radiation. Materials and Methods In this study, 12 ore samples (each mass weighing about 2 kg) were collected from the iron or...

Phase Field Modeling and Simulation of Three-phase Flows

Abstract. In this paper, we derive a thermodynamically consistent phase-field model for flows containing three (or more) liquid components. The model is based on a Navier-Stokes (NS) and Cahn-Hilliard system (CH) which accounts for surface tension among the different components and three-phase contact lines. We develop a stable conservative, second order accurate fully implicit discretization o...

High Temperature Behavior of Dual Phase Steels

Dual phase steels with different martensite volume fraction and morphology were tensile tested at a temperature range of 25 to 5500C. Stress-strain curves of all steels showed serration flow at temperatures of 250 and 3500C, and smooth flow at the other temperatures. Both yield and ultimate tensile strengths increased with increasing testing temperature up to about 450<sup...

Direct Torque Control Strategy for Dual Three Phase Induction Motors

In this paper, a comparison between a classic direct torque control (DTC) and a modified (DTC) of a dual three phase induction machine (SPIM) will be introduced. In this work, the SPIM has a dual three phase windings spatially shifted by θ electrical degree wich is equal to 60◦. SPIM drive has 64 inverter switching states which provide higher possibility in selecting space voltage vectors than ...

Three-dimensional characteristic approach for incompressible thermo-flows and influence of artificial compressibility parameter

In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...
