Flame Height and Plume Centerline Temperature Calculator

This tool calculates the flame height and plume centerline temperatures based on the correlations by Heskestad and McCaffrey.

The flame height correlation by Heskestad is given by L = -1.02D + 0.235(\dot{Q}^{2/5}).

The plume centerline temperature correlation by Heskestad is given by T_0 = 25(\dot Q_c^{2/5}/(z-z_0))^{5/3} + T_\infty, which is valid above the flame height.

The plume centerline temperature correlation by McCaffrey is given by T_0 = 22.3(\dot Q^{2/5}/z)^{5/3} + T_\infty, which is valid above the flame height.

Note: An ambient temperature (T_\infty) of 20 °C is used.

More information on the above equations can be found in the textbook Enclosure Fire Dynamics by Karlsson and Quintiere.

 

This calculator is powered by the free and open source tools Python, Numpy, and matplotlib, and the source code is freely available here.
