Dispersion of water sprays in a transverse air jet and the aging of spray nozzles
This thesis explores spray cooling methods used in the manufacturing process of glass fibers. At the onset of the manufacturing process glass fibers are extruded from a pool of molten glass through an array of holes in a heated bushing plate. Before the fibers can be wound onto a spool, the fibers …

Liquid entrainment from spray distributors for packed columns
… for estimating the total entrainment from spray nozzles used in liquid distributors of packed beds. The model is based on a mathematical representation of the drop size distribution in sprays, and on the drop buoyancy equations. It takes into account flow rates and physical properties of …

Effect of Local Bed Hydrodynamics on the Distribution of Liquid in a Fluidized Bed
… into a bed of hot coke particles through spray nozzles, grouped in several banks at different vertical positions. The main objective of this thesis is to determine whether significant improvements in liquid-solid contact could be achieved by optimizing the location of the spray nozzles. In …

An investigation of some design factors of a steam jet refrigeration unit
… the warm water into the evaporator, namely by spraying the warm water into the evaporator by means of commercial spray nozzles and by spraying the warm water into the evaporator through small holes in a straight piece of pipe. A series of tests was run to determine the effect of the evaporator …

A study into the effects of spray and jet characteristics on flash evaporation system
… a comprehensive insight into the atomization of sprays or jets in seawater flashing spray desalination. Alternatively, most of the earlier research focused at the macro scale whereby the general process of flashing and its performance was studied. Little or no information is available on the …

Performance of Carbon Dioxide Absorption into Monoethanolamine Solution in a Spray Chamber
… due to its high reaction rate with CO2. The spray chamber is one of the most efficient gas-liquid contactors that can be used effectively for CO2 capture. In this thesis, mass-transfer performance of a spray chamber for CO2 absorption into MEA solution was measured experimentally. The …

Water ingestion in jet engines.
… to facilitate injection of water through spray nozzles fitted at the inlet. In the process, new methods were developed for the reliable measurement of static pressure in a wet environment. Compressor pe1formance changes were quantified by measming the overall total-to-static pressure-rise …

Evaluation of trailer thermal environment during commercial swine transport
… by the location and coverage areas of the spray nozzles and fans. When outside temperature ranged from 10 to 20°C (50-68°F), trailer environment was within acceptable thermal limits without misting the pigs. During cold weather, frozen floor conditions were observed, with floor temperature …
