For a multi-component hydrocarbon mixture under supercritical conditions, especially for fuels injected into compression ignition engines, the mechanism transition of dominant mixing mode from evaporation to diffusion is not well established. In this paper, processes six-component fuel (13.16 mol% toluene, 13.81 n-decane, 22.30 n-dodecane, 24.60 n-tetradecane, 14.66 n-hexadecane and 11.47 n-oct...

Evaporation from soil columns in the presence of a water table is a long lasting subject that has received great attention for many decades. Available analytical studies on the subject often involve an assumption that the potential evaporation rate is much less than the saturated hydraulic conductivity of the soil. In this study, we develop a new semi-analytical method to estimate the evaporati...

shallot (allium altissimum regel.) is a medicinal, industrial and perennial plant that has underground tubers. it is one of the most important allium species in iran, which normally grows in semi-cold to very cold highlands. because of being a wild plant, shallot is encounter with water deficit during its growth season. therefore evaluation of water requirement of shallot is important. in order...

The purpose of this paper is to estimate the evaporation rate in the purification of wastewater by aquatic plants with aeration. Evaporation of surface water is important in dewatering processes. In particular, this is true in arid climates, where evaporation rates are high. Aeration is known to enhance the wastewater purification process, but it increases concurrently the water evaporation rat...

The microscopic events engendering liquid water evaporation have received much attention over the last century, but remain incompletely understood. We present measurements of isotope fractionation occurring during free molecular evaporation from liquid microjets and show that the isotope ratios of evaporating molecules exhibit dramatic differences from equilibrium vapor values, strong variation...

A feature of radiation-beam technologies is similar processes associated with phase transformations and chemical reactions that cause changes in the volume matter, accompanied by vibroacoustic energy release distributed through equipment flexible system a wide frequency range (up to 40 kHz high for 150 ms). The signal amplitude accompanying depends on power density process performance. accelera...
