The calculation of the cumulative thermophoretic efficiency of particles in tube flow with nonuniform inlet particle concentration is considered. Using previous results, a simple but exact expression is found for the cumulative deposition efficiency. An illustrative calculation is performed for a specific initial particle distribution with one parameter. The total deposition efficiency is computed as a function of this parameter and the results are compared to the uniform inlet concentration case. It is observed that the deposition efficiency is higher when the initial particle concentration is greater near the tube wall.
