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 ...
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 ...
Comparison of Observed and Simulated Drop Size Distributions from Large-Eddy Simulations with Bin Microphysics
Publisher: American Meteorological Society
Abstract: Two case studies of marine stratocumulus (one nocturnal and drizzling, the other daytime and nonprecipitating) are simulated by the UCLA large-eddy simulation model with bin microphysics for comparison with aircraft in ...
