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...

The objective of this research is to develop an accurate numerical method to be used in showing the deformation of a liquid fuel droplet in a convective field. To simultaneously solve the internal liquid droplet flow field as well as the external gas phase flow field, a nonstaggered rectangular grid system without any coordinate transformation is used. Transition from the gas field to the liqui...

Background. Transmission efficacy of Influenza in aerosols is dependent on environmental factors such as temperature, relative humidity (RH), airflow, andUV-light.We studied the impact of these factors on the recovery of an aerosolized wild-type Influenza virus. Methods. Influenza Avirus (A/WS/33 H1N1) was aerosolized via nebulizer (droplet nuclei) and airbrush (droplet nuclei/droplet mix). Vir...

Testicles were isolated from dromedary camels in a local slaughterhouse at breeding and non-breeding seasons. Sperms were recovered from different parts of the epididymis (caput, corpus and cauda) and stained separately on slide glasses by eosin nigrosin staining method and dried by a hair dryer and carried to the laboratory. In the lab, slides were observed for evaluation of the proportion of ...

The present article aims at developing simple realistic models in order to describe the gaseous removal process of SO(2) by absorption with and without chemical reaction in spray towers. Effects of droplet size, droplet velocity, superficial gas velocity, liquid flow rate and tower height on the performance of such a system are theoretically predicted. Model calculations bring out some very int...

Previous work (Birnberg, Jayroe, Hanson 1982 Plant Physiol 70: 511-516) demonstrated that corn mitochondria (Zea mays L.) can accumulate citrate by a malate- and phosphate-independent proton symporter. This uptake and symport of other ions were investigated. Passive swelling experiments indicated that corn mitochondria can accumulate several other anions by proton symport, but only isocitrate i...
