Effect of sneeze flow velocity profiles on the respiratory droplets dispersion in a confined space: An experimental and computational fluid dynamics study

Physics of Fluids, 2023
In this study, the effects of sneeze velocity profiles, including peak velocity (PV), peak velocity time (PVT), and sneeze duration time (SDT), on the dispersion of respiratory droplets were studied experimentally and numerically. Spatial–temporal datasets of droplet velocity exhaled from several subjects' mouths with different physiological ...

Droplet size and velocity profiles in liquid–liquid horizontal flows

Chemical Engineering Science, 2004
Abstract The size and vertical distribution of drops were studied experimentally in dispersed liquid–liquid pipeline flows. Under most conditions the pattern was dual continuous where both phases retain their continuity and there is entrainment in the form of drops of one phase into the other.

Radial-velocity profile along the surface of evaporating liquid droplets

Soft Matter, 2012
The deposit pattern of drying liquid droplets has a close relationship with the radial-velocity profile along the droplet surface. In this paper, the surface temperature of the droplet is first solved numerically and approximated by a simple analytical form, and an analytical expression for the radial-velocity of the surface flow is then obtained by ...

Spatial droplet velocity and size profiles in effervescent atomizer-produced sprays

Fuel, 1999
Effervescent atomizer produced sprays were studied for application to rotary kiln incinerators. The sprays were characterized by their number averaged droplet velocity profiles, Sauter mean diameter (SMD) profiles, and size-velocity correlations. Spray mass flow rates ranged from 30 to 120 g/s.

Pressure and Velocity Profiles Generated by Laser-Heated Spherical Droplets

1988
When a spherical droplet is irradiated by a light beam the heat released by absorption of light causes expansion of the sphere which gives rise to a photoacoustic effect. The acoustic waveforms generated by Gaussian heating functions can be calculated from convolution integrals.

The gas velocity profile of a free fall atomizer and its relation to solidification microstructure of collected spray droplets of 2014 aluminium alloy

Materials Science and Engineering: A, 1993
Abstract The gas flow field of a free-fall atomizer was measured in three dimensions using hot wire anemometry and corresponding measurements were taken using a Pitot tube to confirm axial flow velocities. The measurements show good agreement with predictions of fluid flow modelling.
