THERMOCOUPLES AND SAMPLE PROBES FOR COMBUSTION STUDIES

The importance and limitations of probe methods for making measurement s in combusting systems are reviewed and discussed in terms of the con tributions that they can make to improve the knowledge and the modelli ng of practical systems. Emphasis is on measurements of temperature, m ajor species and ion concentrations, which are discussed in terms of t he need to determine and minimize probe-induced disturbances in practi cal combusting flows. In addition, errors arising from the difficulty in interpreting the results in turbulent flames are discussed and the review also provides some insight into measurements of time-resolved s calar quantities.
