Sinopsis

A model has been developed for the numerical determination of the combustion rate of a double base (DB) homogeneous solid propellant.The boundary conditions, at the gas-solid interface, are governed by the pyrolysis law of the propellant and by the conservation of the enthalpy heat flux on each side of the interface. The boundary values problem posed by the enthalpy equation associated with there boundary conditions is solved by using a quasi-linearization method.

The heat transfer from the primary flame to the solid surface is numerically determined and related to the solid propellant combustion rate. Results are compared favourably with experimental data obtained by LENGELLE (1) and KUBOTA (2). In particular, the burning rate and the temperature evolution through the reactive zone are well predicted.
