This study is concerned with the statistics of vertical turbulent channel flow laden with inertial
particles for two different volume concentrations (Φ V= 3× 10− 6 and Φ V= 5× 10− 5) at a
Stokes number of S t+= 58.6 based on viscous units. Two independent direct numerical
simulation models utilizing the point-particle approach are compared to recent experimental
measurements, where all relevant nondimensional parameters are directly matched. While
both numerical models are built on the same general approach, details of the …
