A fully one-sided diffuse-interface immersed boundary method for wall-modeled large-eddy simulation
Qian Mao, Yoshiharu Tamaki, Song Zhao +3
Diffuse-interface immersed boundary methods (DIBMs) provide a simple and robust approach for simulating flows involving complex geometries. However, their inherent diffusion effect…
An improved fully one-sided diffuse-interface immersed boundary method with target-value reconstruction for compressible flows
Qian Mao, Song Zhao, Pierre Boivin +1
Although one-sided spreading has been shown to improve the near-wall accuracy of diffuse-interface immersed boundary methods (DIBMs), the effect of its asymmetric kernel support on…
Fluid transport by a single active filament in a three-dimensional two-phase flow
Qian Mao, Umberto d'Ortona, Julien Favier
Micro-scale cilia play a vital role in mucociliary clearance (MCC) in the human respiratory airways. In this numerical study, we examine fluid transport driven by the active beatin…
Hydrodynamic coupling of a cilia--mucus system in Herschel--Bulkley flows
Q. Mao, Umberto d'Ortona, J. Favier
The yield stress and shear thinning properties of mucus are identified as critical for ciliary coordination and mucus transport in human airways. We use here numerical simulations…
