Sublimation and vaporization of an ice aerosol particle in the form of thin cylinder by laser radiation

Mesoscopic Dynamical Model of Ice Crystal Nucleation Leading to Droplet Freezing

“…During the four stages of liquid droplet freezing, the precooling and cooling stages can be estimated by solving the internal heat equation. The physical properties of water and ice were considered: density, ρ * l = 1000 kg m –3 , ρ * s = 917 kg m –3 ; capacity, C v* l = 4.2e6 J K –1 m –3 , C v* s = 1.9e6 J K –1 m –3 ; and thermal conductivity, λ * l = 0.55 J m –1 K –1 s –1 , λ * s = 2.26 J m –1 K –1 s –1 (l for liquid, s for solid, * for reality coefficient; parameters without * are in DPD units) . The changes in these properties with changing temperatures were simplified and held constant.…”

“…l for liquid, s for solid, * for reality coefficient; parameters without * are in DPD units). 32 The changes in these properties with changing temperatures were simplified and held constant. Heat transfer between air and liquid was much smaller than that between a cold surface and liquid, so the heat transfer of ambient air was ignored.…”

Modeling and Simulation of Turbulent Non-Reacting and Reacting Spray Flows

“…In [10], a set of coupled equations for the droplet temperature, radius and beam intensity in the diffusive regime, assuming low-mass-fiux conditions, was set up. Another study of vaporization of laser irradiated droplets was done in [9,10,11]. Experimental studies of vaporization of droplets by irradiation with a pulsed laser can be found in [11,12,14].…”

“…Another study of vaporization of laser irradiated droplets was done in [9,10,11]. Experimental studies of vaporization of droplets by irradiation with a pulsed laser can be found in [11,12,14]. In the case considered here, the vaporization of a large droplet by irradiation with a long-time laser pulse of low energy, the vaporization process is governed by the processes of heat conduction and diffusion of the vapor [10].…”

“…The boundary conditions for the liquid phase equations (17)(18)(19)(20) are The source terms, Sy, Sm, and Se, for the mass, momentum, and energy equations, respectively, needed in Eqs. (11)(12)(13)(14) are given in [20].…”
