| Outline of Final Research Achievements |
In this study, gaseous temperature measurements have been made on the flames propagating the vortex flow. It was found that the flame tip temperature is about 1200degC for various fuel/O2/inert mixture, which indicates that the extension of the flame propagation limits in the vortex flow is attributed to the flame temperature increase through the effects of Lewis number or pressure diffusion. The miniature power system has also developed utilizing the heat transfer enhancement by the vortex flow. As a result, over 20W output was obtained with miniature vortex combustion power system of 5^3cm3, which energy density attained 176mW/cm3. Furthermore, autonomous power system has been developed on which all electrical systems have been exerted by the part of generated power.
