2. Analysis of physical phenomena, characteristic scales and timescales

2.1 Presentation of the main physical phenomena to be taken into account

Unlike the wings of an aircraft, where the aim is to delay the onset of turbulence in order to minimize drag, a highly turbulent flow is sought in the combustion chamber (figure 10 ). This not only promotes fuel atomization and reactant mixing, but also maximizes heat release per unit volume by increasing the flame surface area (notably by pleating).
