Understanding the Spatial Heterogeneity of Global Environmental Change in Mountain Regions

Abstract

A Lagrangian approach is developed for droplet vaporization in turbulent fields, with tw-way coupling between phases. Specific source terms induced by phase changes are described and results are presented for methyl alcohol droplet vaporization in a heated turbulent round jet. A high coupling is observed between production and diffusion processes For the vapour mass fraction and fluid temperatures. Droplet diameter distributions are strongly dependent on the turbulent dispersion and droplet history.
