Sub-micron particle deposition on an isothermal horizontal rod in a turbulent flow system

The available theoretical models for particulate fouling were reviewed and used to explain some of limited fouling data which have been reported. An experimental measurement of the thermophoretic deposition of sub-micron particles on the smooth wall of a circular rod and a simple approximation of a two-dimensional method for predicting the thermophoretic effects on sub-micron particles are introduced. The particles were moving under fully developed turbulent flow conditions, and the investigation focusses on diffusive deposition of sub-micron particles of d(p) = 0.05 mum and d(p) = 0.25 mum in diameter.
