摘要: Abstract The deposition of particles in fully-developed turbulent channel flow has been calculated using large eddy simulation the incompressible Navier-Stokes equations. Calculations were performed for Reynolds numbers 11,160 and 79,400 (based on bulk velocity hydraulic diameter); subgrid-scale stresses parameterized dynamic viscosity model. Particle motion was governed by both drag lift. effect particle-particle interactions as well modification carrier neglected. In agreement with previous studies, LES results show that accumulate near-wall region. Statistical measures from calculations such particle rate are reasonable direct numerical McLaughlin (1989). For identical relaxation times wall units, rates at two nearly identical. Issues relevant to application predicting high also discussed.
