The flow field, consisting of a core region and a boundary layer, was proposed and experimentally tested by Mori and Nakayama (1965) for values of the flow Reynolds number up to 4000. The calculated trajectories are used to predict the distribution of inertia-less particles at a cross-section 9.375 dia downstream of a 90° bend. In addition, the fractions of entering particles deposited by inertial impaction and interception in a 90° bend are computed. The results show that the flow Reynolds number has significant effects on particle deposition in bends. The theoretical predictions for the distribution of particles downstream of a bend and the efficiency of deposition are in good agreement with experimental results reported in the literature.
