Fuel Droplet Evaporation in a Supercritical Environment
This paper reports a numerical investigation of the transcritical droplet vaporization phenomena. The simulation is based on the time-dependent conservation equations for liquid and gas phases, pressure-dependent variable thermophysical properties, and a detailed treatment of liquid-vapor phase equilibrium at the droplet surface. The numerical solution of the two-phase equations employs an arbi...
متن کاملSubcritical and Supercritical Nanodroplet Evaporation: a Molecular Dynamics Investigation
Molecular dynamics simulations are used to investigate the subcritical and supercritical evaporation of a Lennard-Jones (LJ) argon nanodroplet in its own vapor. Using a new technique to control both the ambient temperature and pressure, a range of conditions are considered to define a transition line between subcritical and supercritical evaporation. The evaporation is considered to be supercri...
متن کاملLow-Reynolds-number droplet motion in a square microfluidic channel
In this study, we investigate computationally the low-Reynolds-number droplet motion in a square micro-channel, a problem frequently encountered in microfluidic devices, enhanced oil recovery and coating processes. The droplet deformation and motion are determined via a three-dimensional spectral boundary element method for wall-bounded flows. The effects of the flow rate, viscosity ratio and d...
متن کاملComparative Analysis of a Single Fuel Droplet Evaporation
In this research, the results of comparative analysis of a single fuel droplet evaporation models are presented. Three well-known evaporation models including Spalding, Borman-Johnson and Abramzon-Sirignano models are analyzed using Computational Fluid Dynamic (CFD). The original Spalding model is extended to consider the effects of the Stefan flow, unsteady vaporization, and variable propertie...
متن کاملEvaporation of a Liquid Droplet
Two idealized models for the preheat s tage of liquid droplets are ana lyzed theoretically . These models conta in the effects of transie nt heat conduction and evaporati on. It is assumed that the droplet surface a rea decreases linearly with time. This assumption necessitates the solution of mov ing boundary problems . These models, however, do not consider gas-phase mass transport . In the f...
