Abstract

Preferential droplet vaporization of a 24-component mixture under different ambient temperature, pressure and force convection

Highlights

  • Except some works [7,9] above has mentioned the influence of temperature and pressure on the preferential vaporization, there are rather few studies directly investigating the effects of some dependent parameters on preferential vaporization

  • To take account of force convection effect, the classical Effective Thermal Conductivity/Effective Diffusivity (ETC/ED) droplet evaporation model is utilized to simulate the evaporation of multicomponent droplet

  • In order to efficiently simulate the droplet evaporation under force convection, the “stagnant film theory” and “effective thermal conductive/effective diffusivity” model [14,15] are used in this work

Summary

Introduction

Except some works [7,9] above has mentioned the influence of temperature and pressure on the preferential vaporization, there are rather few studies directly investigating the effects of some dependent parameters on preferential vaporization. Parametrical investigations (temperature, pressure and force convection) about preferential vaporization of multicomponent droplet are carried out. A 24-component mixture, formulated as a surrogate for Chinese aviation fuel RP-3 in prior work [13], is selected as the target fuel. To take account of force convection effect, the classical Effective Thermal Conductivity/Effective Diffusivity (ETC/ED) droplet evaporation model is utilized to simulate the evaporation of multicomponent droplet
