Deposition characteristics of magnesium silicate and calcium carbonate in cooling tower water

Creator:: Lee, Sai Heep
Abstract:: Deposition characteristics of magnesium silicate and calcium carbonate on a heated surface in cooling tower water using city water as make-up was investigated. Flow velocity, bulk temperature and calcium hardness were maintained constant at 5.3 ft/ sec, 95°F and 150 ppm as CaCO₃ respectively whereas surface temperature varied from 105°F...

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...

Surface temperature effects on the fouling characteristics of cooling water

Creator:: Story, Michael Kenneth
Abstract:: A cooling tower system was built and fouling resistances were studied for cooling water flowing over a heated tubular surface. The cooling water studied was formulated in an effort to match industrial cooling water quality. The water used in this study had an average Ryznar Stability Index of 6.23 and...

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...

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...

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...

Single phase turbulent mixing between adjacent channels in rod bundles

Creator:: Galbraith, Kirk Powell
Abstract:: The turbulent interchange of matter between parallel adjacent subchannels in a simulated rod bundle for single phase flow was investigated to determine the effects of mass flow rate and rod spacing. The simulated rod bundle was made by placing six 1-inch diameter rods in a square-square array. The overall test...
