Natural and forced turbulent mixing in rod bundles

Creator:: Jovanovic, Goran N.
Abstract:: The effects of mass flow rate and subchannel configuration on the turbulent interchange between adjacent subchannel in simulated rod bundle were investigated. The simulated rod bundle was made by arranging seven 1.913 cm diameter acrylic plastic rods in an equilateral triangular pattern in a tube 8.89 cm inside diameter. The...

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...

Fouling characteristics of a desalted crude oil

Creator:: Lin, Dah-cheng
Abstract:: The fouling characteristics of a desalted crude oil were investigated in a systematic investigation. There are two main parts in this study, the dry bulk tests (dehydrated crude oil) and the wet bulk tests (to which desalter brine was added). Three barrels of desalted crude oil provided by Amoco Oil...

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...

Effects of water quality and surface temperature on the scaling characteristics of cooling tower water

Creator:: Lahm, Lawrence
Abstract:: The fouling of cooling tower water was investigated as a function of heater surface temperature and water quality. In particular, the effects on fouling of the addition of calcium in excess of the amounts required for saturation were examined. First, the average bulk water temperature was 97 ± 1 degree...

Calcium carbonate scaling characteristics of cooling tower water

Creator:: Coates, Kenneth Edwin
Abstract:: Scaling characteristics of calcium carbonate on a heated surface in cooling tower water was investigated. Bulk temperature was maintained constant at 95°F. Flow velocities and surface temperatures ranged from 3 ft/sec to 10.3 ft/sec and from 105°F to 170°F respectively. City water was used as make-up for two different water...

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...
