Flow and fouling in a pleated membrane filter

Pleated membrane filters are widely used in many applications, and offer significantly better surface area to volume ratios than equal-area unpleated membrane filters. However, their filtration characteristics are markedly inferior to those of equivalent unpleated membrane filters in dead-end filtration. While several hypotheses have been advanced for this, one possibility is that the flow fiel...

Modeling and Design Optimization of Multifunctional Membrane Reactors for Direct Methane Aromatization

Due to the recent increase of natural gas production in the U.S., utilizing natural gas for higher-value chemicals has become imperative. Direct methane aromatization (DMA) is a promising process used to convert methane to benzene, but it is limited by low conversion of methane and rapid catalyst deactivation by coking. Past work has shown that membrane separation of the hydrogen produced in th...

Multi Level Modeling for Engineering Design Optimization

Physical systems can be modeled at many levels of approximation The right model de pends on the problem to be solved In many cases a combination of models will be more e ective than a single model alone Our research investigates this idea in the context of en gineering design optimization We present a family of strategies that use multiple models for unconstrained optimization of engineering de...
