1. Large Eddy Simulations of Model-Scale Turbulent Atmospheric Boundary Layer Flows.
PMID:日期:2017This paper presents large eddy simulations (LES) of model-scaled neutrally stratified atmospheric boundary layer (ABL) flows for structural engineering applications and examines their statistical properties. A one- -equation eddy model is used for the subgrid-scale (SGS) motions, and a wall shear model is applied on the ground. The mean streamwise velocity profile is approximately logarithmic, yet near the ground a mismatch persists because of the limited accuracy of the SGS model. The second moments of the turbulence represent well the underlying physics. The spectra of the velocity components at a point are consistent with commonly accepted expressions. The spatial coherences decay exponentially as functions of reduced frequencies. The results suggest that, except for the mean velocity near the ground, the ABL turbulence statistics can be well represented by large eddy simulations with simple SGS and wall models.

2. Dynamics of Stress Fibers Turnover in Contractile Cells.
PMID:日期:2012-03-01Numerous experiments have shown that contractile cells like fibroblasts adapt their internal structure to their microenvironment by generating and orienting a network of stress fibers (SFs). This phenomenon has been modeled in previous studies with stability analysis through calculation of the fiber's potential or strain energy, where SFs are assigned a constant elasticity. Recent experiments have shown that the elasticity in SFs is rate dependent, resulting in a different stress fiber organization under constant or cyclic stretching. Here, a thermodynamical model that describes the anisotropic polymerization of the contractile units into SFs via the calculation of the mechanochemical potential of the two constituents is proposed. The stretch-dependent part of the SF potential is made of two terms that describe the passive and active behavior of the SF. In this paper, it is shown that the contributions of these two terms vary widely under constant or cyclic stretching as the SFs exhibit a rate-dependent elasticity and lead to two very different anisotropic SF organizations. It is further demonstrated that the substrate stiffness as well as its Poisson's ratio and anisotropy play a crucial role in the formation and organization of the SFs, consistent with what has been observed in various experiments.
