Abstract

A micro-thermocouple, microphones and microphone probes were employed to provide detailed information on key ongoing processes in a premixed swirl flame. High frequency pressure and temperature measurements were carried out to identify temperature field and acoustic characteristics of a swirl stabilized premixed flame. The local distributions of fluctuating pressure and temperature were measured in different regions, in and around the flame. Noise sources were investigated by using microphone probes and microphone arrays. Temperature and pressure fluctuations were examined both inside and outside the flame boundary. Sensor network used here is essential for the development of advanced combustion systems for it can provide detailed temporal and spatial information that can allow for better control to achieve higher efficiency and performance.
