Data from: Numerical and experimental study of pyrophoric activated metal Mg surface combustion characteristics

The combustion of multi-hole pyrophoric activated metal belongs to solid
combustion and the combustion mechanism is quite complex, which is a
difficult problem to be solved. Once the pyrophoric activated metal
contacting with oxygen, the oxygen diffuses to the interior of the
activated metal within plenty of holes and reacts with it, which enlarges
the contact area with oxygen. Consequently, the whole combustion is
serious and the temperature rises rapidly. To study the combustion
mechanism of chaff, surface heat balance equation is established in this
work by taking Mg as the activated metal. To solve this equation, the
chaff adiabatic wall temperature distribution is computed by computational
fluid dynamics (CFD) in the presence of high speed airflow. Then, chaff
surface temperature distribution is obtained by solving the heat balance
equations. Finally, numerical and experimental results via infrared (IR)
thermal imager are compared to demonstrate the effectiveness of the
established equation.
