DPM - Why do the particles not vanish?

Johannes

Hi there,

when simulating the injection of fuel into a combustion chamber, I've got a problem. The particles mass and diameter do not reach zero. The particles size was about 25E-06 m and only reaches about 2.5E-06m. Why is this so? The temperature is high enough and the length of the computational domain should be big enough to let all particles to evaporate. There seems only to happen evaporation at the beginning and then it stops. Another problem is, that the particles minimum temperature does not match my initialization temperature. I initialize the particles with a temperature of 293.15 K into hot air of about 800K. Nevertheless the lowest temperature of the particles in the particle tracking modus are about 370 K. I would be glad, if someone can help me.

Greetings, Johannes.
