Abstract:A multi-point ignition system with an electric igniter was designed and experimental investigations were carried out by using this analogue ignition device to solve the charge problems in the powder chambers with the over 3m length.The corresponding mathematical and physical models were established to describe the multi-point ignition process in this analogue ignition device.The MacCormack difference equation was used to obtain the numerical solutions as follows:The pressure distribution and void ratio and solid and gas velocities.And the multi-point ignition process was analyzed.The calculated results are consistent with the experimental ones and the algorithm is effective.
Keywords:mechanics of explosion  long powder chamber  two-phase flow  multi-point ignition
