Abstract
Progress to the correlation of particle deposition velocity in turbulent pipe flow is presented. The developed model accounts for the Brownian diffusivity and inertia effects and is extended to cover the influence of the flow velocity by including Reynolds number in the correlation. The experimental data and previous proposed models are used in comparison of predicting particle deposition rate. It is shown that the new model of deposition velocity is in good agreement with the experimental data and numerical simulations. Further the aerodynamics has significant influence on the deposition rate and should be concerned when the process of particle migration and deposition is addressed. The deposition efficiency, the measurement tool of particle deposition rate in this work, increases with the increase of diameter for large particles, and with the decrease of diameter for submicron particles. Other factors addressed in this work are effects of particle to fluid density ratio, pipe diameter and the surface roughness. The results showed that increase in density ratio makes the deposition rate of submicron particles to increase too whereas no significant effects is noticed for large particles. Carrier pipe size is studied and the deposition rate curve shifts right with decreasing in pipe size. Finally, the deposition rate of particles is found to increase with increase in surface roughness.
