Hello everyone.

I am currently simulating an combustion process, where Kerosene gets premixed with Oxygen and burnt in an combustion chamber. To simulate that, I inject Kerosene Droplets at the same inlet like oxygen.

I run the simulation transient with eddy-dissipation concept. After the first timestep just one droplet evaporates and ignites, but after that, it just tracks the same number of droplets the whole time and no evaporation takes place after that.

My DPM settings are

*Interaction with continuous phase: Yes
*Max. Number of Steps: 500
*Step length factor: 5
*Unsteady Particle tracking: Yes
*Particle time step: 1e-7 s

The time-step length of the tranisent simulation is 1e-5 s

I am basically lacking the settings to make the droplets evaporate and ignite with the oxygen.
