Nucleate boiling of various fluids in a thermosiphon reboiler

Creator:: Oufer, Lounes
Abstract:: A study of nucleate boiling of water, four alcohols and three ethanol-water mixtures was conducted in a vertical thermosiphon reboiler. The test section consisted of a 1/2- inch diameter electrically heated stainless-steel rod jacketed by a 15-inch long pyrex glass tube. Two different inside diameters of the glass tube corresponding...

A study of climbing-film flow characteristics of various liquids and air in an annular duct

Creator:: Vierra, George Joseph
Abstract:: Momentum transfer in climbing-film flow in an annular duct was investigated. Air and various liquids, with a wide range of viscosities and surface tensions, were investigated. The two phases flowed co-currently upward, the liquid climbing as a thin film on the inner wail while the outer wall remained dry. The...

Turbulent flow of liquid-liquid dispersions : drop size, friction losses, and velocity distributions

Creator:: Ward, John Philip
Abstract:: The momentum transfer characteristics of liquid-liquid dispersions were studied under conditions of turbulent flow in a cirular conduit. Experiments were conducted to obtain drop size, friction factors and velocity profiles for three organic phases dispersed in water. The test sections consisted of straight copper tubes 1-inch OD and 0.830-inch ID....

The effect of capillary tube dimensions on the viscosity of liquid-liquid dispersions in laminar flow

Creator:: Ichikawa, Shinya
Abstract:: The purpose of this research was to study the effect of capillary tube dimensions on the apparent viscosity of an unstable dispersion of two immiscible liquids. The study was limited to laminar flow at a constant temperature. The dispersions were composed of a commercial solvent, Shellsolv 360, manufactured by the...

Friction losses for water flowing in non-circular ducts

Creator:: Mohandes, Abdolhosein
Abstract:: Friction factors were measured for water flowing in ducts made up of two rods held between two flat plates. Three rod diameters of 0.50, 1.00 and 1.50 inches were used. The spacings between rods varied from 0.0 to 0.32 inch. It was found that the concept of hydraulic diameter was...

A study of two-phase liquid-liquid flow in pipes

Creator:: Soot, Peet Mati
Abstract:: The pressure drop for two-phase liquid-liquid flow is theoretically predicted for each flow regime. Empirical correlations, which are applicable in all flow regimes, are also presented for holdup as well as pressure drop. The experimental study covered bubble and drop flow regimes. The discontinuous phase was injected by nozzle into...

Drop size distributions produced by turbulent pipe flow of immiscible liquids

Creator:: Collins, Stanley Browning
Abstract:: Drop size distributions produced by the turbulent pipe flow of dispersions of immiscible liquids were measured photographically. A mathematical model was developed which predicted both the shape of the experimentally observed distributions and the experimentally observed kinetics of the breakup process. The mutually saturated water and organic phases were pumped...

Heat transfer between moving beds of solids and a vertical tube

Creator:: Obuskovic, Nevenka S.
Abstract:: Heat transfer to moving packed beds of solids has been studied extensively but predictions are usually specific to the experimenter's own equipment. In order to obtain a more general predictive equation, the heat transfer coefficient was measured for a single vertical tube immersed in a moving packed bed of glass...
