Annular gas-liquid two phase flow is widely encountered in the nuclear industry. Various combinations of techniques have been employed in annular gas-liquid two phase flows to measure the flow parameters (e.g. liquid film thickness, gas volume fraction and the phase flow rates). One of the most useful techniques which has proven attractive for many multiphase flow applications is the electrical...

Local exhaust ventilation (LEV) systems and integrated collectors were designed and implemented in a mining company in order to control emitted air pollutant from furnaces. The LEV was designed for capture and transition of air pollutants emitted from furnaces to the integrated collectors. The integrated collectors including four high efficiency Stairmand model cyclones for control of particula...

Droplet size is a fundamental parameter for Venturi scrubber performance. For many years, the correlations proposed by Nukiyama and Tanasawa (1938) and Boll et al. (1974) were used for calculating mean droplet size in Venturi scrubbers with limited operating parameters. This study proposes an alternative approach on the basis of artificial neural networks (ANNs) to determine the mean droplet si...

In this article we have made an attempt to survey some results on performance of jet ejector. The literature is also reviewed to pursue further work in this area. Key wordsHEVS, EVS, jet ejector, performance of venture scrubber, characteristics of jet ejector, efficiency

The Cape ventilator (Penlon Ltd) still remains one of the most widely used ventilators in intensive therapy units (ITU). However, when low fractional inspired oxygen concentrations (F IO2 ) are prescribed, particularly when associated with low minute volumes (V̇ ), the required supplemental oxygen flow is small. Flows less than 2 litres/min are not uncommon. For example; an F IO2 of 0·35 and a V̇...
