Mass Transfer Characteristics of Large Oscillating Drops
The literature related to mass transfer of solute from large, oscillating drops in liquid-liquid systems has been critically reviewed. A thermostatically-controlled spray column, provided with mirrors, was used to study the hydrodynamics and mass transfer characteristics of single large oscillating …

Mass Transfer Characteristics of the Submerged Liquid Jet
Mass transfer characteristics of a liquid jet in a liquid continuous phase have been studied using a captured jet technique. A vertical jet was formed at the centre of a glass sided square-section cell of 102mm x 102mm x 305mm which held the stationary continuous phase. The technique allowed the …

Experimental evaluation of heat transfer characteristics of silica nanofluid
The laminar convective heat transfer characteristics were investigated for silica nanofluid. An experimental loop was built to obtain heat transfer coefficients for single-phase nanofluids in a circular conduit in laminar flow regime. Thermal conductivity and viscosity measurements were conducted …

Mass transfer characteristics of two-aqueous-phase liquid-liquid mixtures
Mass transfer rates were studied using the falling drop method. Cibacron Blue 3 GA dye was the transferring solute from the salt phase to the PEG phase. Measurements were undertaken for several concentrations of the dye and the phase-forming solutes and with a range of different drop sizes, e.g. …

Boiling heat transfer characteristics of steam generator U-tube fouling
The boiling heat transfer characteristics of steam generator u-tube fouling deposits were identified by developing a boiling heat transfer model and determining its accuracy through the comparison of calculated and experimental results. Magnetite deposits were fabricated in the laboratory and were …
