ABSTRACT

A two-dimensional analysis for droplet heat and mass transfer in forced convection turbulence fluctuations is presented. The computational model is based on the volume-of-fluid method and PLIC free-surface tracking method, which can capture the droplet deformation accurately. The rate of droplet evaporation is computed by the gradient of vapor mass fraction in the interface cells. Numerical predictions of lifetime of droplet evaporation match experimental data quite well. The effects of turbulent intensity and oscillatory flow frequency on heat and mass transfer of a droplet are investigated. Furthermore, much attention is paid to the droplet deformation and wake length. The numerical results show that the droplet lifetime decreases with increasing turbulence intensity and decreasing oscillatory frequency. In addition, droplet deformation due to the turbulence fluctuations in forced convection plays an important role in affecting droplet evaporation.
