High-load Combustion
Numerical analysis of ultra-micro combustor for UMGT was carried out by comparing with an experiment result. First of all, we examined the flat-flame ultra-micro combustor with porous medium injector. We succeeded in simulating this porous medium by the equivalent gaseous channel with limiting temperature, and confirmed the reliability of analytical model adopted. Then, we elucidated the effects of equivalence ratio, wall temperature and combustor size on the flow field and flame structure. The energy density becomes large with the decrease in combustor size. Furthermore, we examined the slit type combustor by comparing with the flat-flame ultra-micro combustor. The combustion efficiency is very high for the slit type combustor, so that the perfect combustion is achieved. Especially, the high energy density and small heat loss are achieved for the combustor with inner slit, so that high-load combustion can be realized.
