Turbulent mixing across adjacent subchannels in packed rod bundles using conductivity measurement

Creator:: Chan, Pui Yuen
Abstract:: Turbulent mixing across adjacent subchannels in packed rod bundles was studied using conductivity measurement and sodium chloride solution as the tracer. Single phase water was the fluid investigated. The packed rod bundles were seven stainless steel tubes, 1.905 cm in diameter and 152.4 cm long, arranged in hexagonal close-packed configuration...

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...

Incipient boiling and burnout heat flux for subcooled water flowing in annuli containing heated concentric wires

Creator:: Nolan, Lawrence Lyle
Abstract:: Incipient boiling and burnout heat fluxes were studied for sub-cooled forced convection annular flow. Small wires varying from 0.010 to 0.020 inch in diameter were used as the inner core of the annulus and a one inch ID glass tube 24 inches long was used as the outer tube. This...

Nucleate boiling in a vertical annular duct

Creator:: Daniel, Tyrone
Abstract:: Nucleate boiling of water in a vertical annulus was studied. The test section was entirely of stainless steel construction and was formed by a length of stainless steel tubing with a stainless steel heater rod centered in it. Two test sections with length to diameter ratios of 18 and 33...

Calcium sulfate scaling under boiling conditions

Creator:: Cates, David Lawrence
Abstract:: A bench-scale thermosiphon reboiler system was constructed end used to investigate the scaling behavior of aqueous calcium sulfate under flow boiling conditions. Scaling data were collected at constant heat flux from eight experimental runs. Five different constant heat fluxes were used ranging from 45000 to 93000 Btu/hr. ft², in increments...

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...

Turbulent heat transfer in annuli at large diameter ratios

Creator:: Unzicker, William Frank
Abstract:: Heat transfer from the inner wall of an annulus to subcooled water in turbulent parallel flow was studied. The inner core of the annulus consisted of wires varying from 0.0019 to 0.0197 inch in diameter. The outer tube consisted of a 1.01 inch diameter glass tube 24 inches long. Diameter...
