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.

Prof Palmore just returned from a very fulfilling trip to Texas. There he visited collaborator Yuaho Xu at Prairie View A&M University and delivered at talk on "High-fidelity fluid dynamics simulation: recent results on droplet evaporation." He also attended the US National Combustion Meeting, this year hosted by Texas A&M University, and presented a poster on recent work in CAMPhyRE.
This work was supported by Virginia Tech's Institute for Critical Technology and Applied Science, via the grant "Effects of Gravity on Droplet Evaporation and Combustion of Liquid Fuels" for which Profs. Palmore and Xu are co-PIs. |
