On the physics of aerobreakup
Web17 de jul. de 2024 · Theoretically, the physics of aerobreakup is controlled by the Ohnesorge number (Oh) of the droplet, which compares the effects of liquid viscosity and surface tension, and the Weber number (We) at freestream conditions, which describes the ratio of disruptive inertial to restorative interfacial forces. Web2 de ago. de 2024 · In this study, an investigation targeting the early-stage deformation of liquid drop in airflow is carried out. We of the test conditions is of the order of 10 3 –10 4, and a shock tube facility is employed to produce the high-speed flow. The development of the drop is recorded through direct high-speed photography.
