Description
Understanding the dynamics of droplet breakup in high-speed flow fields is critical for many aerospace applications such as liquid fuel injection into high-speed crossflow or weather encounters with high-speed vehicles. In such applications, thermophysical properties such as surface tension, viscosity, etc. as well flow parameters (Mach number) will drive the droplet breakup regime. The objective of this work is to implement diffuse background illumination (DBI) to quantify sessile droplet breakup. A shock tube will be employed to simulate high-speed flow conditions by generating shock waves of various strengths. Both head on and side imaging will be implemented to provide further insight to the breakup dynamics. Weber number will be used to identify breakup regimes. Center of mass calculations will be performed using the high-speed imaging data.
