Mathematical simulation for non-equilibrium droplet evaporation

Gas-phase saturation and evaporative cooling effects during wet compression of a fuel aerosol under RCM conditions

“…A2. There is very little difference in overall evaporation behavior for the d 0 = 8 lm condition, which is consistent with other studies [21][22][23] which demonstrated that larger droplets are less affected by thermodynamic non-equilibrium conditions. In Fig.…”

“…However, these errors appear to be modest ($5-15%) and the trends in the modeling results using the interface equilibria prescription appear to be comparable to those observed with a refined modeling approach where gas kinetic effects are taken into account (e.g., see Appendix A, as well as Refs. [20][21][22][23]). The droplet and surrounding gas-phase are assumed to be spherically-symmetric, and thermal and concentration gradients within the droplet are taken into account.…”

Composite structures with gradient of permeability to be used in heat pipes under microgravity

“…There are several limiting factors for the thermal performance of a heat pipe on which attention of researcher is aimed: optimization of the fins shape [6], adding of nanoparticles in conventional fluids [7], accurate study of evaporation phenomena [8]. The pumping performance of the capillary pump is determined by the pore diameter of the porous material and the dimensions of the evaporator.…”

Theoretical and experimental investigations of the interaction of hot gases with liquid in closed volume

“…In paper [9], numeric research of liquid droplet evaporation in a heated gas is described, based on the concentrated model; in addition, experimental research to investigate analytical modeling is described. In work [10,11], an analytical model of the non-equilibrium evaporation of liquid droplets by using the Navier-Stokes system of equations is discussed. Numerical simulations of liquid droplet combustion in turbulent flows of gaseous oxidant are described in [12][13][14].…”
