The particle rebounding characteristics of a gas–particle flow over a cylindrical body and an in-line tube bundle arrangement is investigated. With the aim of adopting both numerical and experimental approaches, the mean particulate flow patterns, comprising both incident and rebound particles resulting from the impact of particles on solid walls, are examined. Experimentally, a two-dimensional Laser-Doppler Anemometry (LDA) technique is used to measure the instantaneous incident and rebound particle velocities in the immediate vicinity of body surfaces. Computationally, the Reynolds-Averaging Navier-Stokes equations are solved for the continuum gas phase; the results are used in conjunction with a Lagrangian trajectory model to predict the particle-rebound characteristics. For a single tube model, the computational observations, also confirmed through experiment, reveal a particle rebound zone where the mean particulate flow pattern is significantly modified due to the contribution of the rebound particles during particle-wall impact interaction. For the in-line tube bundle model, particles being rebounded from the first row of tubes at upstream migrated downstream and impinged the other tubes in an extremely complex and random disposition. Analysis of the effect of the above-mentioned parameters on the rebounding particle flow characteristics has provided a better understanding on the behaviour of particulate flow impinging on curved solid wall bodies.
