چکیده مقاله:

In this paper, a new version of an existing burning model of binary mixture of magnesium and sodium nitrate particles has been developed. Modifying some parts of the model such as particle burning time, thermo physical properties of combustion products, and the mixture density, the burning rate has been predicted. Then, the effect of composition,magnesium articles size, initial temperature of the mixture, and pressure on burning rate has been discussed. Finally, using the results of the model, the burning rate ballistic parameters such as coefficient, exponent, and temperature sensitivity have been derived and compared to the existing experimental values. The comparison shows good agreement between the predicted and experimental data in composition and pressure dependencies of the burning rate.
