How does wire thickness affect particle motion in hot wire powder experiments?

[M.KALEM]

I am doing experiment about escaping powder. In this experiment I am immersing hot wire into the water and investigating the motion of floating particles. What is the importance of thickness of wire? And what do you think about other parameters?

The wire diameter will affect the heat transfer rate, but without a better explanation, it is kind of hard to give you any more useful advice.
