Overview: In the paper, the numerical model is presented in detail, and some examples of its application to the experimental configuration are discussed. At high altitude, the operating critical conditions make the ignition and the relighting of jet engine combustors more difficult to control. The objective of ONERA is to develop a computational tool to predict ignition inside the turbojet combustor, according to the internal two-phase flow field and the igniter s location. To study the flame kernel initiation, a one-dimensional model has been developed to predict the ignition of a spherical two-phase kernel when submitted to the electrical spark.
