A benchmark for particle-laden turbulent duct flow: A joint computational and experimental study
A turbulent duct flow laden with small heavy inertial particles (Re τ≈ 570, St+≈ 50, d p+≈
0.3, St≈ 12, and dp/η≈ 0.17) is studied computationally and experimentally. We examine
whether a long development section can be modeled using a short periodic domain. This
simplification is not valid if the development section is too short (less than 25–50 duct-height
in our case), the periodic simulation is not integrated long enough (less than O (1000) large-
eddy turnover time in our case), or the effective mass loading ratio is not adjusted correctly …
