Liquid-Liquid dispersion in Cocurrent Flow Through Orifice

experimental investigation of power consumption, mass transfer coefficient and flow regime in gas-liquid dispersion systems

Experimental studies of liquid-liquid dispersion in a turbulent shear flow

We built up an experiment to study liquid-liquid dispersions in a turbulent Taylor-Couette flow, produced between two counterrotating coaxial cylinders, of radii ri = 100mm and ro = 110mm (gap ratio η = ri/ro = 0.909). The useful length is L = 185mm. There is a space of 10mm between the cylinders bottom ends and a free surface on the top. The cylinders rotation rates ωi and ωo can be set indepe...

Ju l 2 00 7 Experimental studies of liquid - liquid dispersion in a turbulent shear flow

We study liquid-liquid dispersions in a turbulent Taylor–Couette flow, produced between two counterrotating coaxial cylinders. In pure Water and in counterrotation, Reynolds numbers up to 1.4× 10 are reached. The liquids we use are a low-viscous Oil and pure Water or a Sodium Iodide solution with a refractive index matched to that of Oil, in order to get transparent dispersions. We first charac...

Parameters characterising the pulsing flow for cocurrent flow of gas and foaming liquid in a pressurised trickle-bed reactor

The aim of the present work was to experimentally determine the parameters characterizing the pulse flow of liquids through bed i.e. the frequency of pulsation and the velocity of pulses travelling along the bed and next to work out the correlation equations enabling their assessment. The research was carried out in a pressure reactor (pressures up to 2 MPa) having 0.05 m in diameter and being ...

Modelling Liquid Flow Through Carbon Nanotubes

In this paper, the structure of a liquid and character of its flow in carbon nanotube is investigated. A review of the literature and the results of experiments show that the simulation of fluid flow for nanoscale systems should be based on the continuum hypothesis taking into account the quantized character of the liquid in the length scale of intermolecular distances. Consideration of the flo...
