A novel formulation of multi-component drop evaporation models for spray applications

Droplets and Sprays

“…In the case of multi-component droplets we can impose a similar condition for all individual components in the gas phase. Following [81], this condition can be presented as:…”

“…d is the evaporation rate of species k (following [81] and in contrast to Equation (15) we assume thatṁ (k) d ≥ 0 during the evaporation process), ρ total is the total density of the mixture, including ambient gas.…”

“…Having introduced new variable ζ = R d /R, the general analytical solution to Equation (54) was obtained in the form [81]:…”

“…To take into account the effects of multi-component droplet movement on droplet heating and evaporation, in [81] (as well as in a number of other papers, e.g. [83]) it was assumed that there is no interaction between evaporating species.…”

Evaporation of a Droplet of a Heated Colloid Solution on a Horizontal Structured Wall

“…High wall temperatures lead to a heat transfer crisis [5,6]. Typical features of evaporation of multi-component liquids were considered in [7]. Evaporation of water often produces an adverse effect on the parameters of various technologies.…”
