Steady State Modeling and Dynamic Analysis of Film Blowing
Perturbation analysis, which has never been applied to film blowing, was used to explore the effect of system disturbances on the process. Results showed that perturbations related to heat transfer and inflation pressure were more significant than the effect of die swell. In addition, crystallinity …

Applications of Reservoir Limnology Theory and Steady-State Modeling to Eutrophication Management in Beaver Lake, Arkansas
… explicit data were not available. United States Geological Survey (USGS) monitoring data collected at the dam, and three additionally overlapping sites, from 2001 to 2015 were used to develop and test the hindcast models. Residuals of the modeled-measured USGS data suggested that variation …

The nuclear spin dependence of the reaction of H3+ with H2 and the proposed spectroscopic investigation of HO2+
… indicate that the regulation of the nuclear spin states of H$_3^+$ is not well understood. The nuclear spin configuration of interstellar H$_3^+$ is postulated to be governed by the reaction of H$_3^+$ $+$ H$_2$ $\rightarrow$ H$_2$ $+$~H$_3^+$ and is one of the topics explored in this work. This …

Heterogeneous nucleation of active pharmaceutical ingredients on polymers : applications in continuous pharmaceutical manufacturing
… system when mass transfer kinetics dominated. Steady state modeling based on the first principle approach was performed using a combination of Navier Stokes Equations and diffusion-convection mass transport equations. The modeling result demonstrated that for mass transfer from a moving fluid …

Resonant Cross-Commutated Dc-Dc Regulators with Omni-Coupled Inductors
… on with zero voltage within a wide load range. A state-space model was developed to calculate the voltage gain, voltage stresses, and current stresses. Design guidelines for the rccBuck converter operating at continuous voltage mode or discontinuous voltage mode are provided. The design …

Numerical Analysis of Flow and Heat Transfer through a Lean Premixed Swirl Stabilized Combustor Nozzle
… The work was also extended to reacting flow modeling (using a partially premixed model) for a specific Reynolds number. These efforts were carried out in order investigate the flow behavior and also characterize convective heat transfer along the combustor wall (liner). Additionally, several …
