CHAPTER 6

TUBULAR FLAME CHARACTERISTICS OF MINIATURE LIQUID FILM COMBUSTORS

Derek Dunn-Rankin

6.1 INTRODUCTION

This chapter is inspired by the opportunity for using tubular flames in miniature liquid-fueled power systems. Recognizing that a high-performance portable power system should provide up to 1000 W for tens of hours, it is straightforward to conclude that a device based on the combustion of liquid fuel is needed.1 The superiority of liquid fuel combustion for high-power density portable power derives from the inherent chemical energy storage density of combustible liquids. There are challenges, however, to efficiently evaporating and burning liquid fuels in small volumes. All miniature combustors suffer from an increasing surface-to-volume ...
