Flame stabilization is a critical issue in designing high-performance gas turbine engines and combustors owing to the increased demand for high-power and low-emission combustion and the trend toward the utilization of low-grade fuels. As commonly seen, flame stabilization is generally achieved with the addition of a pilot flame, bluff body, and swirling flow. Although these methods have been shown to be successful on flame stabilization, the considerable complexities of incorporating these enhancements in an industrial-scale system hinder the utilization of these approaches in various applications. Non-thermal plasma is a promising technique to enhance combustion efficiency and reduce emissions due to its unique capability of producing active species and heat, which in turn modifies the transport processes in combustion reactions. The overall objective of the proposed study is to investigate the impact of plasma discharge on the flame stabilization of a lifted turbulent jet diffusion flame. Of specific interests are the effect of plasma application and the characteristics of plasma discharge on the lift-off height and the stability range of a lifted turbulent non-premixed flame.
