Simulation of closed vessel combustion using the 2D ICT-Cellular-Combustion-Algorithm

A model using the ICT-Cellular-Combustion-Algorithm (ICCA) is presented which makes it possible to simulate closed vessel combustion of propellants with arbitrary cross sectional geometry. ICCA enables the user to explore new possible propellant geometries for which it is not possible to calculate analytical form functions. The model uses the 2D version of ICCA that uses 2D bitmaps as input data and simulates the 2D form function which is then linked to the variables that are needed to simulate 3D propellant combustion. It is shown that the simulation results for standard propellant geometries match the results from the new standard interior ballistics code SimIB perfectly.
