Abstract This paper proposes a novel method to measure each constituent of an oil–gas–water mixture in water continuous flow, typically encountered many processes. It deploys dual-plane electrical resistance tomography sensor for measuring dispersed phase volume fraction and velocity; gradiomanometer flow density meter drift flux model estimate slip velocities; with absolute pressure temperatur...

For a Czochralski growth of Ge crystal, thermal fields have been analysed numerically using the three-dimensional finite volume method (FLUENT package). The arrangement used in a real Czochralski crystal growth lab included a graphite crucible, heat shield, heating device, thermal insulation and chamber including two gas outlets. We have considered two cases for calculations, which are configur...

We examine the linear stability of gravity-driven flow a viscoelastic fluid film down an inclined plane. The is modeled using Oldroyd-B constitutive equation and, therefore, exhibits constant shear viscosity and positive first normal stress difference in viscometric shearing flows; latter class flows includes aforesaid film-flow configuration. show that configuration susceptible to two distinct...

Effect of altitude is discussed in the unsteady separation of multi stage rockets. Axisymmetric, unsteady and turbulent Navier stokes equations are solved numerically. The governing equations are split into a hyperbolic inviscid part and a parabolic diffusion part. The hyperbolic part is solved by an explicit second-order time and space of Godunov-type scheme. Moving mesh and moving boundary al...

This work is concerned with stability and receptivity analysis as well as studies on control of the laminar-turbulent transition in boundary-layer flows through direct numerical simulations. Various flow configurations, both twoand threedimensional boundary layers, are considered to address flow around straight and swept wings. The aim of this study is to contribute to a better understanding of...

An experimental and “numerical study (first part of this study) was carried out to investigate the solidification process in a copper continuous strip casting process. The model has been tuned by results (i.e. cooling water flow measurements, temperature measurements metallographic analysis). Further, have used possibility improved productivity. In report (second pattern molten during as manufa...

in this research, the effect of surface roughness and bubble injection on skin friction and hydrodynamic drag force has been numerically considered. this research is based on taylor-couette flow. considered flow includes two concentric cylinders which internal cylinder is movable and external is immovable. the effective equations on the flow includes: equations of momentum, continuous, turbulen...

Magnetohydrodynamic (MHD) mixed convection flow of Cu–water nanofluid inside a two-sided lid-driven square enclosure with adiabatic horizontal walls and differentially heated sidewalls has been investigated numerically. The effects of moving lids direction, variations of Richardson number, Hartmann number, and volume fraction of nanoparticles on flow and temperature fields have been studied. Th...
