Abstract For a single methanol droplet in quiescent environment,the evaporation characteristics were simulated using the non-equilibrium evaporation model.The effects of the ambient pressure,temperature,and the droplet radius and temperature at the initial droplet temperature condition were investigated.The results indicate that the droplet equilibrium temperature increases with the increase of ambient pressure.The droplet evaporates faster when the ambient temperature is lower than the critical temperature and it evaporates slower when the ambient temperature is higher than the critical temperature.With the ambient temperature rising,the droplet evaporates faster and the equilibrium temperature increases.The initial droplet temperature has certain influences on the droplet vaporization in transient heating process and has little effect on the droplet vaporization in equilibrium process.
