Structure of Evaporating Diesel Sprays
Performance of compression ignition engine is known to be spray characteristics related. Precise experimental information on fuel sprays is of utmost importance to model the fuel spray formation and its development in the engine combustion chamber. The previous experimental work of the present author on non-evaporating sprays produced by using a FIAT single-hole orifice type nozzle and a distri...
متن کاملComputations of Turbulent Evaporating Sprays
A computational study of turbulent evaporating sprays is reported. The major focus is to study the structure of turbulent evaporating sprays and to examine the sensitivity of their vaporization behavior to transient liquid-phase processes. Three models considered to represent these processes are the thin-skin, infinite-diffusion, and diffusionlimit models. Favre-averaged equations with a k-s-g ...
متن کاملEvaporating drops of alkane mixtures
Alkane mixtures are model systems where the influence of surface tension gradients during the spreading and the evaporation of wetting drops can be easily studied. The surface tension gradients are mainly induced by concentration gradients, mass diffusion being a stabilising process. Depending on the relative concentration of the mixture, a rich pattern of behaviours is obtained. keywords Movin...
متن کاملEvaporating black holes and entropy.
We study the Hawking radiation for the geometry of an evaporating 1+1 dimensional black hole. We compute Bogoliubov coefficients and the stress tensor. We use a recent result of Srednicki to estimate the entropy of entanglement produced in the evaporation process, for the 1+1 dimensional hole and for the 3+1 dimensional hole. It is found that the one space dimensional result of Srednicki is the...
متن کاملSalt stains from evaporating droplets
The study of the behavior of sessile droplets on solid substrates is not only associated with common everyday phenomena, such as the coffee stain effect, limescale deposits on our bathroom walls , but also very important in many applications such as purification of pharmaceuticals, de-icing of airplanes, inkjet printing and coating applications. In many of these processes, a phase change happen...
