A Langmuir sorption model incorporating a second step of
irreversible absorption was applied to a model soil system. The column
was packed with cellulose triacetate; pulse and step input tests with
3,4-dichlorophenol were performed; the effluent concentration was
measured by electron capture detector gas chromatography and sorption
rate constants were...
This thesis examines the transient and steady-state temperature performance
of a rotary regenerative heat exchanger. In contrast to previous
studies on this problem, fluid flow in the circumferential direction was
considered. Appropriate modeling was included to measure the effect of
carry-over on the differential equations describing mass and energy
conservation....
An experimental investigation was conducted to
better understand the heat transfer process with natural
convection from an array of uniformly heated horizontal
cylinders to mercury.
Five assembly geometries were studied, these being
the single horizontal cylinder, two cylinders with spacing
ratios S/D = 2,3 and 4, (S represents the center-to-center...
