The framework for a simulation model which describes the dispersion of individual droplets of water containing viable microbes is presented. The model accounts for physical, chemical, biological, and measured meteorological parameters of each droplet at each of many short time steps. Repeating the modeling process for many droplets will simulate a cloud of droplets. The model is compared with t...

Liquid dispersion on a wire mesh is phenomenon that utilized in many industrial applications, such as rotating packed beds. It very simple method of liquid atomization without need for complex nozzles. This research focuses an elementary case crossing two wires. Experiments were carried out wind tunnel to elucidate the influence counterflow air velocity sheet and droplets. High-speed camera was...

Violent respiratory events play critical roles in the transmission of diseases, such as coughing and sneezing, between infectious susceptible individuals. In this work, large-scale multiphase flow large-eddy simulations have been performed to simulate jet from a human's mouth carrying pathogenic or virus-laden droplets by using weakly compressible smoothed particle hydrodynamics method. We expl...

Perilipin-1 (Plin1), a prominent cytoplasmic lipid droplet (CLD) binding phosphoprotein and key physiological regulator of triglyceride storage and lipolysis in adipocytes, is thought to regulate the fragmentation and dispersion of CLD that occurs in response to β-adrenergic activation of adenylate cyclase. Here we investigate the dynamics and molecular determinants of these processes using cel...

Dispersion of spray droplets and the modulation of turbulence in the ambient gas by the dispersing droplets are two coupled phenomena that are closely linked to the evolution of global spray characteristics, such as the spreading rate of the spray and the spray cone angle. Direct numerical simulations (DNS) of turbulent gas flows laden with sub-Kolmogorov size particles, in the absence of gravi...

Measurements of size-resolved cloud condensation nuclei (CCN) concentrations, subsaturated hygroscopic growth, size distribution, and chemical composition were collected from March through May, 2007, in the remote Boreal forests of Hyytiälä, Finland, as part of the European Integrated project on Aerosol Cloud Climate and Air Quality Interactions (EUCAARI) campaign. Hygroscopicity parameter, κ ,...

The surface and emulsifying properties of a commercial pea protein isolate in oil-in-water model emulsions the role insoluble residues emulsion stability were investigated. Droplet size distribution, flocculation index, microstructure, coverage evaluated. fraction positively contributed to proteins’ properties, allowing formation with higher dispersion degree, especially at low concentration, a...
