[en] The deposition rate of submicron particles from turbulent gas streams was investigated and found to be consistent with a correlation derived by Kader and Yaglom. The data include deposition measurements of particles having diameters ranging from 0.041 to 0.2 μm and roughness configurations varying from a spacing to height ratio, P/K of 2 to 25. The results indicate that the correlation developed by Kader and Yaglom can be used to predict submicron particle deposition over a wide range of roughness geometries. Their approach can also be extended to estimate deposition rates of molecules and molecular clusters on rough surfaces so that the entire range of rough wall deposition from molecular size to submicron particles can be estimated with good precision.
