Drops, globules of a liquid in another liquid, are extremely important in many natural processes and industrial applications. The purpose of this study was to devise a method to measure the terminal velocity of drops rising in water due to buoyancy, and to compare observed values with the theoretical. Two questions were explored: (1) Do these drops continue to accelerate upward from a depth of ...

Abstract Terminal velocity approximation is appropriate to study the dynamics of a gas–dust mixture with solids tightly coupled gas. This work reconsiders its compatibility physical processes giving rise resonant streaming instability in low-dust-density limit. It shown that linearized equations have been commonly used within terminal actually exceed accuracy this approximation. For reason, cor...

The relationships between mean terminal velocity and volume diameter of different hydrometeors, as well how they change with background aerosol concentrations have been investigated numerical simulations tropical deep convection from the Weather Forecast Research Model (WRF), coupled spectral bin microphysics. results showed a positive correlation either mass-weighted (Vm) or number-weighted (V...
