in this research the effect of two different methods of carcass chilling (immersion and evaporative) in the poultry industrial slaughter line on microbial load and carcass weight changes was studied. for sampling, after evisceration, each carcass weighted and rinsed with 250 ml of sterile water in a plastic bag. 25 ml of rinses water was taken and into sterile scaled container sent to laborator...

In this study, crystallization phenomena were investigated by real-time in situ observation of seeded droplets under evaporation using a self-developed hot-stage platform. Ternary solutions at eutonic conditions 25 °C for the following systems: NaCl–KCl–H2O, NaCl–CaSO4–H2O, and NaCl–Na2SO4–H2O. Evidence epitaxial growth was found aqueous NaCl–KCl NaCl–Na2SO4. Sodium chloride nucleated grew epit...

We consider theoretically, computationally and experimentally spontaneous evaporation of water and isopropanol drops on smooth silicon wafers. In contrast to a number of previous works, the solid surface we consider is smooth and therefore the droplets’ evolution proceeds without contact line pinning. We develop a theoretical model for evaporation of pure liquid drops that includes Marangoni fo...

Water dripping into subterranean cavities within fractured porous media is studied in order to improve estimates of dripping rates, drop sizes, and chemical composition of droplets that could affect long-term integrity of waste disposal canisters placed in caverns. Steady state liquid flux in fracture surfaces supported by flow in partially liquid-filled grooves and liquid films in adjacent pla...

In this report, experimentsmimicking some aspects of cloud-clear-air mixing in a laboratory chamber are discussed. A saturated plume containing small droplets of water (a surrogate of an atmospheric cloud) is mixedwith unsaturated environmental air in order to study effect of evaporative cooling at the interfaces between cloudy and clear air filaments on small-scale turbulence. Two components o...

In order to explore plasma-assisted turbulent mixing in aerospace engines, the dielectric barrier discharge plasma actuation for of fuel droplets and oxidant air a ramjet combustor was studied using computational fluid dynamics. A two-way coupling discrete realized by Eulerian–Lagrangian simulation, action on flow modeled body force. The results show that can rearrange recirculation zone behind...

In this paper, the application of evaporative cooling for refrigeration cycle to reduce power consumption in hot climates is emphasized. Experimental and analytical investigations were performed in order to specify the effect of evaporative cooling condenser instead of the commonly used air cooling condenser in window-air-conditioners. Evaporative condenser can reject more heat, thereby preve...

Over the last decades, a fabulous variety of synthetic superhydrophobic surfaces have been created, offering unique anti-wetting properties. A significant focus for these has on their stay-dry and self-cleaning However, unless in saturated environment, water droplets lose mass through evaporation this itself is field interest, which illustrated by flood recent studies surface contamination pote...
