Preliminary modelling of reaction chamber rupture
In this section a preliminary modelling of a reaction chamber rupture in Section 2 of the S-I cycle is
described. The S-I cycle model utilised is detailed in Brown (2009) and the PBMR-268 model used is
detailed in Seker (2005). The discharging gas is modelled using the source model presented in Bird
(1960) for choked gas flows. The composition of the discharging gas is shown in Table 2. A graphical
representation of the discharge is shown in Figure 10. The discharge rate model is:
