Congratulations to CAMPhyRE student Meha Setiya on publishing "Quasi-steady evaporation of deformable liquid fuel droplets" in the journal International Journal of Multiphase Flow! This work investigates the effect of droplet deformation on its evaporation rate under convective flow conditions. These studies utilize interface capturing Direct Numerical Simulation (DNS). This technique accurately simulates the droplet deformation due to aerodynamic stress, allowing for a new and more detailed analysis of droplet evaporation to be performed. The results suggest a correlation between the total evaporation rate and droplet shape with the most deformed droplet seeing a 20% enhancement in evaporation rate. The work also demonstrates how analytical theories such as Palmore (Journal of Heat Transfer, 2022) can be used to explain this phenomenon.
