A review of measurements of heat flux density applicable to the field of combustion

The techniques that have been developed for the measurement of heat flux density are reviewed briefly. These techniques may be divided into two broad categories: (1) indirect methods based on the fundamental theories of heat transfer and (2) direct methods using a heat flux density sensor. Various methods are compared in order to stimulate further research and the development of sophisticated techniques for the measurement of heat flux density in the field of combustion.
