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 ...

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 ...

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 ...

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 ...

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 ...
