Mass transfer in annular liquid jets in the presence of liquid flow rate fluctuations

Heat and mass transfer in annular liquid jets: I. Formulation

Heat and mass transfer phenomena in annular liquid jets are analyzed at high Reynolds numbers by means of a model derived from the governing equations that takes into account the e€ects of surface tension and boundary conditions at the gas± liquid interfaces and the large di€erences between the thermal and mass di€usivities, densities, dynamic viscosities, and thermal conductivities between gas...

Investigation of mass transfer coefficients in irregular packed liquid-liquid extraction columns in the presence of various nanoparticles

In the present study, the effect of various nanofluids on mass transfer coefficients in an irregular packed liquid-liquid extraction column was investigated. The chemical system of toluene–acetic acid–water was used. 10 nm SiO2, TiO2 and ZrO2 nanoparticles with various concentrations were dispersed in toluene-acid acetic to provide nanofluids. The influence of concentration and hydrophobicity/h...

Heat and mass transfer in annular liquid jets: II. g-jitter

The e€ects of g-jitter on heat and mass transfer in underpressurized, annular liquid jets are analyzed numerically as a function of the amplitude and frequency of the gravitational modulation by means of a mapping technique that transforms the timedependent geometry of these jets into a unit square and a conservative ®nite di€erence method. It is shown that the pressure coecient, gas concentra...

Investigation of Mass Transfer Coefficient under Jetting Conditions in a Liquid-Liquid Extraction System

In this research mass transfer coefficient under jetting regime in different directions (from dispersed to continuous and continuous to dispersed phase) has been studied using an experimental setup. n-Butanol-succinic acid-water with low interfacial tension has been selected as experimental chemical system. The effects of various parameters such as jet velocity, nozzle diameter and the heig...
