Application of a new scheme of cloud base droplet nucleation in a spectral (bin) microphysics cloud model: sensitivity to aerosol size distribution [PDF]
Atmospheric Chemistry and Physics, 2016 A new scheme of droplet nucleation at cloud base is implemented into the Hebrew University Cloud Model (HUCM) with spectral (bin) microphysics. In this scheme, supersaturation maximum Smax near cloud base is calculated using theoretical results ...

Numerical Simulation of Microscale Oblique Droplet Impact on Liquid Film
Aerospace, 2023 The oblique impact of microscale water droplets on liquid film is numerically investigated. Two-phase flow problems are simulated using three-dimensional incompressible Navier-Stokes equations, and the level-set method is employed for capturing the gas ...

Dissipative Particle Dynamic Simulation of Oil-Water Two-Phase Flow in Quartz Slits
Geofluids, 2023 Aiming to study the characteristics and mechanism of oil-water two-phase flow, based on the method of dissipative particle dynamics (DPD), meso-scale models of pressure-driven flow in quartz slits with width of 5-15 nm were simulated.

Vibration Induced Transport of Enclosed Droplets
Micromachines, 2019 The droplet response to vibrations has been well characterized on open substrates, but microfluidic applications for droplets on open systems are limited by rapid evaporation rates and prone to environmental contamination.

Vertical wind velocity measurements using a five-hole probe with remotely piloted aircraft to study aerosol–cloud interactions [PDF]
Atmospheric Measurement Techniques, 2018 The importance of vertical wind velocities (in particular positive vertical wind velocities or updrafts) in atmospheric science has motivated the need to deploy multi-hole probes developed for manned aircraft in small remotely piloted aircraft (RPA ...

On Modeling of Spray G ECN Using ROI-Based Eulerian-Lagrangian Simulation
Frontiers in Mechanical Engineering, 2022 A numerical study has been carried out to understand the effects of Unsteady Reynolds Averaged Navier-Stokes (standard k ― ε and RNG k ― ε model) and large eddy simulations (LES) on a multi-hole gasoline direct injection (GDI) system.

Effect of Hydrophilicity/Hydrophobicity of the Injector Wall on Atomization Performance
International Journal of Aerospace Engineering, 2022 Hydrophilicity/hydrophobicity is a common physical property of the material. Water droplets roll on lotus leaf, and a lot of dust and dirt on the surface of the lotus leaf will be taken away, playing a certain cleaning role.
