Microgravity Ignition Experiment on a Droplet Array in High-Temperature Low-Speed Airflow

摘要

The objectives of this study were to observe ignition events and to measure ignition times of a droplet array of n-decane placed in a high-temperature low-speed airflow under microgravity field. Due to the difficulty of making droplets of the same size within a short period of time in a drop capsule, imi- tation droplets made of porous ceramic balls soaked with n-decane were used.
