Predicting Behavior of Gas-Solids Systems for Non-Uniform Fluidization
(The American Society of Mechanical Engineers (ASME), 2023)A new method was developed to predict the pressure drop and minimum fluidization velocity as a function of inlet gas velocity for multicomponent fluidized beds. The method attributes the changing bed composition during the ... -
Mixing in Low Reynolds Number Reacting Impinging Jets in Crossflow
(The American Society of Mechanical Engineers (ASME), 2023)Previous efforts to model uranyl fluoride formation in an impinging jet gas reactor underpredicted spatial mixing and overpredicted chemical conversion into particulates. The previous fluid dynamics model was based on the ... -
Correlations Describing Laminar Hydrodynamic Development in a Circular Pipe
(The American Society of Mechanical Engineers (ASME), 2023)Computational fluid dynamics (CFD) is employed to study incompressible and steady laminar flow in the hydrodynamic entrance region of circular pipes for a wide range of Reynolds numbers. Dimensionless analytic expressions ... -
Hydrodynamic Characteristics of Textured Microchannel Flow
(The American Society of Mechanical Engineers (ASME), 2023)Microchannel flow is of great interest across many disciplines and applications, from biochemical diagnostics to thermal management systems. Nonetheless, such flow requires large pumping power due to its small cross-sectional ... -
A Novel Method to Achieve Fast Multi-Objective Optimization of Hydrostatic Porous Journal Bearings Used in Hydraulic Turbomachine
