RISDispersion of Heavy Particles by Turbulent Motion
Publisher: American Meteorological Society
Abstract: Accurate prediction of heavy particle dispersion in turbulent flows requires a simultaneous consideration of particle's inertia and particle's drift velocity. A mathematically simple and physically comprehensive analysis ...
The Other Metallic Phase in Spent Nuclear Fuel: A Complete Thermodynamic Evaluation of the U–Pd–Rh–Ru System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During burnup of nuclear fuel, fission products accumulate. Post-irradiation examination of burned up nuclear fuel has revealed the presence of several phases, namely, the fuel matrix of UO2, with dissolved oxides present; ...
Flow Modulation by Finite Size Neutrally Buoyant Particles in a Turbulent Channel Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A fully mesoscopic, multiplerelaxationtime (MRT) lattice Boltzmann method (LBM) is developed to perform particleresolved direct numerical simulation (DNS) of wallbounded turbulent particleladen flows. The fluid–solid ...
Comments on “Droplets to Drops by Turbulent Coagulation”
Publisher: American Meteorological Society
Improved Formulations of the Superposition Method
Publisher: American Meteorological Society
Abstract: Two formulations of an improved superposition method are proposed for studying droplet?droplet hydrodynamic interactions. The formulations make explicit use of the boundary conditions on the surface of the two interacting ...
Growth of Cloud Droplets by Turbulent Collision–Coalescence
Publisher: American Meteorological Society
Abstract: An open question in cloud physics is how rain forms in warm cumulus as rapidly as it is sometimes observed. In particular, the growth of cloud droplets across the size gap from 10 to 50 ?m in radius has not been fully ...
In Memoriam: Dave Stock—Teacher and Pioneer Researcher in Multiphase Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is with profound sadness that we report the death of a much loved and greatly respected colleague and friend—Professor David E. Stock, Washington State University.In a career spanning nearly 40 years “Dave” performed ...
Theoretical Formulation of Collision Rate and Collision Efficiency of Hydrodynamically Interacting Cloud Droplets in Turbulent Atmosphere
Publisher: American Meteorological Society
Abstract: A methodology for conducting direct numerical simulations (DNSs) of hydrodynamically interacting droplets in the context of cloud microphysics has been developed and used to validate a new kinematic formulation capable of ...
Study of Local Turbulence Profiles Relative to the Particle Surface in Particle Laden Turbulent Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As particleresolved simulations (PRSs) of turbulent flows laden with finitesize solid particles become feasible, methods are needed to analyze the simulated flows in order to convert the simulation data to a form useful ...
Probability Distributions of Angle of Approach and Relative Velocity for Colliding Droplets in a Turbulent Flow
Publisher: American Meteorological Society
Abstract: Prediction of the effect of air turbulence on statistics relevant to a collision?coalescence process represents a key challenge in the modeling of cloud microphysics. In this paper, collision-related statistics for ...
