Variable particle properties

Please login with a confirmed email address before reporting spam

Hello,

i am modelling a tube that is heated externally (heat flux mode). The air stream that is flowing inside the tube is heated from the hot walls. I want to add few particles in the airstream so i use particle tracing module, and i want to ask the followings:

1. Is it possible to use a temperature dependent particle density, but at the same time to preserve the particle mass. I want to increase the particle diameter in terms of temperature (through a desirable equation) but at the same time have constant mass of the particle and thus decrease its density. There is also an equation for determination of particle density in terms of temperature, if this helps.

2. It is possible to import an equation for particle mass change in terms of its temperature?

Thank you
