I am currently studying the deposition on heat exchangers due to the presence of solid ash particles and vapours in hot flue gas.

I am currently using DEFINE_DPM_BC on the surface of the cylinder (heat exchanger) to study the particle hits but I read several papers where they used DEFINE_DPM_EROSION. I tried to use it but with some problems.

If anyone is using this UDF I would like to ask some questions.

Thank you,

Chiara
