Abstract
ABSTRACT The flow field, particle trajectory, and deposition around a surface-mounted ribbon have been studied numerically. For obtaining the flow field, the time-average Navier-Stokes equations together with the two-equation k-e model of turbulence were solved numerically based on SIMPLE algorithm. The trajectory of particles was obtained by solving the equation of particle motion that included the inertial, viscous drag, and gravity forces. The Stokes (Stk) and gravity numbers (Nsg) were introduced for interpreting the particle transport around the ribbon. The target efficiency with respect to stokes number at zero gravity was calculated and compared with the experimental data. It is seen that except for small deviation between numerical results and experimental data in the range of small Stokes number, the agreement was very good. Particles are deposited around the ribbon due to inertial impaction and gravity force. The dominant deposition mechanism depends on Stokes and gravity numbers. The cumulative...
