    • Accuracy of bed-load transport models in eddy-resolving simulations 

      D’Alessandro, Gianmarco; Hantsis, Zvi; Marchioli, Cristian; Piomelli, Ugo (Elsevier, 2021-04-28)
      This work investigates the accuracy of commonly used bed-load transport models when applied in combination with high-resolution Navier-Stokes solvers. Empirical bed-load models predict the transport rate of sediments based ...

    • Roughness Effects on Scalar Transport 

      Hantsis, Zvi; Piomelli, Ugo (American Physical Society, 2020-11-18)
      We have studied the transport of a passive scalar for passive scalar with Prandtl numbers near unity in a plane channel with rough walls. The study was carried out by direct numerical simulations of the Navier-Stokes ...
