Two-dimensional stable lattice Boltzmann simulation of turbulent flow in wavy walled channel
AIP Advances, 2023 In recent years, the lattice Boltzmann equation has developed into a promising technique for computational fluid dynamics (CFD). The lattice Boltzmann model (LBM) approach is derived from the Boltzmann equation and kinetic theory, as opposed to the ...

Protein Corona Formation on Soft Nanocarriers Under Biomimetic Circulatory Flow
Advanced Materials Interfaces, EarlyView.A biomimetic venous circulation system is developed to study protein corona formation on soft nanocarriers under physiological shear. Liposomes, PLGA nanoparticles, and lipid‐polymer hybrid nanoparticles acquire largely shared but material‐dependent protein coronas that alter surface properties and suppress cellular uptake, highlighting the importance ...

On the Reynolds number expansion for the Navier–Stokes equations [PDF]
Nonlinear Analysis: Theory, Methods & Applications, 2014 In a previous paper of ours [Nonlinear Anal. 2012] we have considered the incompressible Navier-Stokes (NS) equations on a d-dimensional torus T^d, in the functional setting of the Sobolev spaces H^n(T^d) of divergence free, zero mean vector fields (n > d/2+1).
