| Abstract: | Integrated igniter design based on the ACIS 3D geometric modeler and HOOPS display modeler is presented.The main dimension of the structure of the igniter was estimated,the performance of the igniter was indicated and time graphics was displayed.A new mathematics model was developed to calculate mass flux and the pressure time history relationship.In order to validate the new model,an example was given.The numerical simulation method was used to analyze the ignition transient.The result is in agreement with... |
