A Theoretical Study on Ignition Mechanisms of Liquid Propellants.

Abstract

Two possible mechanisms for the accidental ignition of liquid propellants are studied: (i) The heating of the liquid surrounding a strongly compressed gas bubble, and (ii) The heating due to viscous dissipation in a rapidly compressed drop. For the first problem the heating of the gas is calculated precisely rather than estimated on the basis of an adiabatic model. For the second problem proper allowance is made for the temperature dependence of the liquid viscosity. In general, the results indicate that ignition is in principle possible, although marginally so. This finding is generally consistent with experiment, and it may explain why it is difficult to deduce definite conclusions from the available experimental evidence.
