Abstract

Study on two-stage ignition of two interactive droplets in flame spread over n-decane droplets in microgravity

Highlights

  • Droplet combustion has been studied to elucidate the mechanism of spray combustion, which is used in many combustors

  • This study focused on the cool flame appearance and two-stage ignition during flame spread over n-decane droplets, and further investigated whether two-stage ignition could occur in flame spread over some combinations of n-decane droplets at 0.3 and 0.4 MPa in microgravity

Summary

Introduction

Droplet combustion has been studied to elucidate the mechanism of spray combustion, which is used in many combustors. Two droplets were heated by burning of droplets to investigate whether two-stage ignition occurs by the interaction of the cool flames.
