Simulation of airborne microbial droplet transport.

Performance Evaluation of a Curved Type Vane Separator at Different Plate Spacings in the Range of 25 to 35mm Using Numerical Simulation

In this paper, the turbulent air droplet flow inside a single passage of a curved type vane separator has been studied numerically. The simulation is based on the Eulerian - Lagrangian method. For turbulent air flow calculations, a computer code was developed to solve the Reynolds Averaged Navier Stokes (RANS) equations together with the equations of Reynolds Stress Transport Model (RSTM) o...

ERDC/CRREL TR-08-20 - Simulation of Fog Oil Deposition During Military Training Operations

In this study we evaluate the ability to simulate deposition of a fog oil (Standard Grade Fuel Number 2 or SGF2) obscurant on the ground using the SCIPuff aerosol transport model. Model results are compared to actual deposition of fog oil measure on the ground during two military training exercises in Alaska. One exercise took place during late summer; the other occurred during midwinter. The r...

بررسی غلظت باکتری ها در هوای داخل بیمارستان مرکز طبی کودکان تهران

Background and Objectives: Atmospheric transport is a key mode of microbial dispersal and the transmission of airborne microbe can have significant impacts on human health. The main objective of this study was to determine the concentrations of airborne bacteria in a children.s hospital.Materials and methods: Three sampling points were selected. Airborne bacteria were collected with 6 days inte...

Reduction of Parasitic Currents in Simulation of Droplet Secondary Breakup with Density Ratio Higher than 60 by InterDyMFoam

Spatial dynamics of airborne infectious diseases.

Disease outbreaks, such as those of Severe Acute Respiratory Syndrome in 2003 and the 2009 pandemic A(H1N1) influenza, have highlighted the potential for airborne transmission in indoor environments. Respirable pathogen-carrying droplets provide a vector for the spatial spread of infection with droplet transport determined by diffusive and convective processes. An epidemiological model describi...
