The rate of evaporation of drops of dibutyl phthalate and butyl stearate of radius approx. 0*5 mm. has been studied by means of a microbalance over a range of atmospheric pressures down to approx. 0*1 mm. of mercury. Wide departures from Langm uir’s evaporation formula were found to oceur a t these low pressures, bu t results are in good acoordance with the theory of droplet evaporation advance...

The previously developed kinetic model for droplet heating and evaporation into a high pressure air is generalised to take into account the combined effects of inelastic collisions between molecules in the kinetic region, a nonunity evaporation coefficient and temperature gradient inside droplets. It is pointed out that for the parameters typical for Diesel engine-like conditions, the heat flux...

A droplet deposited on a rough, lyophilic surface satisfying the imbibition condition, results in spontaneous spreading and hence complete wetting. However, in this thesis, we demonstrate that this wetting behavior can be altered by superheating the substrate such that droplets can reside in a non-wetting state due to evaporation. Photolithography and deep reactive ion etching were used to fabr...

The process of fuel droplet evaporating is one the most important factors that directly affect efficiency combustion process. Therefore, current study reviews previous studies focused on evaporation a drop fuel. review divided into points. first part concerned with modeling under different initial condition and temperature droplet. second present experimental measuring time droplet, as well sha...
