The present study propose an evaluate formula based on the n-τ model for combustion oxcillation fueled by methane and hydrogen in a micro turbine combustor. Instead of a constant value of the pressure-interaction index n (in the previous study, usually n = 0.05), we use a modified index n; which was calculated with considering a relationship between laminar flame speed and heat release rate, in which laminar flame speed was calculated by software based on chemical kinetics. Acoustic instabilities were obtained by this evaluation formula and were compared with the experiment results. As a result, the evaluation formula proposed in this study can predict more accurately than the previous one.
