Settling strongly modifies particle concentrations in wall-bounded turbulent flows even when the settling parameter is asymptotically small
We explore the role of gravitational settling on inertial particle concentrations in a wall-
bounded turbulent flow. While it may be thought that settling can be ignored when the …

Investigating the effect of turbulence on hemolysis through cell-resolved fluid-structure interaction simulations of individual red blood cells
G Rydquist, M Esmaily - Physical Review Fluids, 2024 - APS
Existing hemolysis algorithms are often constructed for laminar flows that expose red blood
cells (RBCs) to a constant rate of shear. It remains an open question whether such models …
