Conclusions

  1. 1.

    A method has been developed for measuring the radiant flux density (q) in the flame of a burning condensed substance using microcalorimeters with low thermal inertia.

     
  2. 2.

    The effect of aluminum content and aluminum particle size on the radiant flux density has been investigated for a model stoichiometric mixture of ammoninum perchlorate and polyformaldehyde. It has been shown that q increases with increase in pressure and aluminum content. A mechanism is proposed for the increase in q with increase in pressure.

     
  3. 3.

    The emissivity ε of burning particles of aluminum and corundum in the flame of the compositions investigated has been estimated; at 40 at, ε=0.13−0.15.

     
  4. 4.

    Fine thermocouples have been used to study the effect of the radiant flux on measurements of the temperature distribution at the surface of the burning compositions investigated and it is shown that this effect may be neglected.
