The rate of burning of colloidal propellants [PDF]

Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1932
Abstract Two papers have recently appeared in which a theoretical law is derived for the burning of colloidal propellants, and in each case the theory is supported by experimental results. Yamaga proves that the rate of burning along the normal is proportional to the pressure of the surrounding gases, ’whereas Crow and Grimshaw prove ...

Nitramine propellants [PDF]

, 1978
Nitramine propellants without a pressure exponent shift in the burning rate curves are prepared by matching the burning rate of a selected nitramine or combination of nitramines within 10% of burning rate of a plasticized active binder so as to smooth ...

Effect of Semi-Transverse Ventilation Velocity on Combustion Characteristics of Pool Fire Sources in a Scaled Tunnel

Fire
Compared to longitudinal ventilation, there are few studies on fire source development under semi-transverse ventilation. This work studied the influence of semi-transverse ventilation on the combustion characteristics of fire sources in a scaled tunnel.
