The effective
thermodynamic temperature in the observation space as measured by a specific sensor for a specified element
(in
).
The temperature of a flame (or other plasma) is not homogeneous. It is usually lower
at the borders of the flame. It is therefore appropriate to speak of an effective
temperature which represents an average value of all temperatures throughout the observation
space. The flame temperature depends on several factors such as: kind of plasma, kind
of gas or gas mixture and
concentration gradient of the
thermometric species in the observation space.
