Drainage of static and translating foam films
Drainage of a mobile, symmetric, plane-parallel thin liquid film between two gas bubbles (foam film) is studied. An analytical solution for the rate of thinning of such a liquid film with an insoluble surfactant and having ...
Modeling and optimization of a two-stage regenerator fluid catalytic cracking unit
In Petroleum refining, the Fluid Catalytic Cracking Unit (FCCU) is the critical stage in the processing of heavy hydrocarbon oils into more valuable gasoline and lighter products. In the FCCU process, the catalyst becomes ...
Transient permeate flux analysis, cost estimation, and design optimization in crossflow membrane filtration
A generalized model is formulated to predict the time-dependent permeate flux by extending previous models to include the particle transport mechanisms of Brownian diffusion, shear-induced diffusion, inertial lift and ...
Elucidation of the formation and decomposition of clathrate hydrates of natural gases through gas solubility measurements
Through isobaric temperature ramping experiments, the solubility of pure methane, ethane, propane, carbon dioxide gases and a methane-propane gas mixture in pure liquid water has been measured. The experiments are conducted ...
In vivo phosphorus-31 and carbon-13 nuclear magnetic resonance spectroscopy to study cellular metabolism
Nuclear magnetic resonance spectroscopy has emerged as a valuable tool for engineers for noninvasive, real-time studies of cellular metabolism. Two applications of NMR for studying cellular metabolism were investigated in ...
Removal of carbon dioxide and water using a solid amine adsorption bed for extended space flight
An enhanced solid amine based regenerative CO$\sb2$ and H$\sb2$O removal system is being used for the shuttle extended duration orbiter (EDO) missions. A computer model was developed to predict the adsorption of carbon ...
