Applications Of Cfd Simulations On Chemical Processing Equipment Designs, Gongqiang He

LSU Doctoral Dissertations

The objective of this work is to achieve process intensification by seeking optimal equipment design with CFD investigations. In this work, two projects on chemical equipment design have been discussed.

The first project is on design and optimization of fractal distributor in a novel ion-exchanger. Flow distributors are adopted extensively by chemical industry to distribute an incoming process stream uniformly to the downstream equipment. Currently, the performance of chemical equipment installed with conventional distributor is severely undermined due to poor flow distribution. For conventional distributors such as spray nozzle distributors, their design concept is based on maintaining very high pressure …

Characterizing The Hydrodynamics Of A Meandering River Neck Cutoff, Christopher Turnipseed

LSU Master's Theses

Meandering river systems often experience a geomorphic phenomenon known as a neck cutoff. The White River of Arkansas has recently undergone several neck cut offs, which have provided a unique opportunity to collect field measurements of the first two years after the opening of the cutoff. In this study the field data was complemented with hydrodynamic simulations to assess the significance of different flow conditions. The findings suggest that flood events play a substantial role in the geomorphic adjustment of the river to the cutoff.
