This study investigates the deformation behavior of two tandem liquid droplets subjected to a traveling normal shock wave using high-fidelity numerical simulations and advanced image processing techniques. Three configurations, with droplet spacings of 1.5, 3, and 6 diameters, were analyzed. The 4.8 mm droplets were subjected to a Mach 1.47 shock wave. These findings underscore the critical role of droplet spacing in shock-induced deformation processes, highlighting how tortuosity and deformation metrics can inform the design of more effective fuel injection strategies in advanced propulsion systems. The application of image processing techniques in analyzing droplet dynamics further enhances the understanding of these complex phenomena.This work was supported by the Naval Surface Warfare Center via Grant: #N00174-22-1-0009.
