On reduced-order modeling of drug dispersion in the spinal canal [PDF]
Fluids and Barriers of the CNSThe optimization of intrathecal drug delivery procedures requires a deeper understanding of flow and transport in the spinal canal. Numerical modeling of drug dispersion is challenging due to the disparity in time scales: dispersion occurs over 1 hour ...

Error of large-eddy simulation in the wall pressure fluctuation of a turbulent channel flow
Theoretical and Applied Mechanics Letters, 2021 We analyze the error of large-eddy simulation (LES) in wall pressure fluctuation of a turbulent channel flow. To separate different sources of the error, we conduct both direct numerical simulations (DNS) and LES, and apply an explicit filter on DNS data
