thermal / fluid
 

Dear friends
I have some starting problem in my work
for example The gas contains carbon particles which flows through the pipe. The pipe inner surface temperature is gas temperature. Outside pipe temperature is forced to maintain at room temperature. i would like to do simulation .Please give your valuable suggestions

Sounds straight forward. What are you trying to learn from this analysis?

I would like to see the carbon deposit in the inner wall of the tube

What makes it deposit? Is it simply the slip velocity of the particles, or is there some attractive force which makes it stick?
