A canonical co-axial round-jet two-fluid atomizer where atomization occurs over a wide range of momentum ratios: $M=1.9 - 376.4$ is studied. The near field the spray, droplet formation process takes place, characterized and linked to dispersion in far jet. Counterintuitively, our results indicate that low-momentum regime, increasing gas phase leads less dispersion. critical ratio order $M_c=50$...

for evaluation of citric acid and citrate effects on bovine epididymal protoplasmic droplets, fifty bovine testes were collected in the october 2007 till june 2008 from urmia slaughterhouse and transported to the laboratory in a cool container filled with 5 °c ice pack. caudal epididymis was incised and sperm cells were put into petri dishes containing hams f10 media with 10% fetal calf serum (...

Iceland contains active dust regions within high-latitude, cold-climate environments. An abundant supply of particulates < 10 µm in diameter (PM10) is available its extensive glacial outwash plains and through widespread transport deposition volcanic ash with hydrophobic tendencies. The climate notably wetter than located hot deserts, so that additional processes governing emission must be cons...

COVID-19 can be easily transmitted to passengers by inhaling exhaled droplets from the infected person in a bus. Therefore, studying droplet dispersion would provide further insight into mechanism of virus transmission and predict risk infection among on In this research, bus equipped with air-conditioning was employed as research object. To determine path, concentration distribution, escape ti...

where L is the liquid water content, and ρw is the density of water. In effect, these studies implicitly assume the only effect of aerosols on cloud microphysical properties is to increase N, and re can be parameterized by Eq. (1) for monodisperse droplet size distributions. Eq. (1) has also been used in the parameterization of re. However, available data suggests the spectral shape of the clou...
