From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Secondary Flow near an Undulatory Surface Induced by Wall Blocking Effect
Journal of Fluid Science and Technology, 2007 Secondary mean motions of Prandtl's second kind near an undulatory surface are explained in terms of the turbulent blocking effect and kinematic boundary conditions at the surface, and the order of magnitude is estimated. The isotropic turbulence is

Theoretical aspects of homogenous isotropic turbulence [PDF]
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2004 We review some recent advances on the problem of fully developed turbulence within the mathematical and physical points of view. From the mathematical perspective, we discuss a framework which has been developed for the rigorous treatment of the conventional statistical theory of turbulence and address some of the rigorous results which have been ...

Advanced Materials Technologies, EarlyView.ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

Forward and backward multi-particle dispersion in homogeneous isotropic turbulence
Nihon Kikai Gakkai ronbunshuTurbulent diffusion in homogeneous isotropic turbulence is numerically investigated using the direct numerical simulation (DNS). The four-dimensional turbulence database allows us to track fluid particles not only in the forward direction of time but ...

The Polymer Effect on Nonlinear Processes in Decaying Homogeneous Isotropic Turbulence
Advances in Mechanical Engineering, 2013 In order to study the polymer effect on the behavior of nonlinearities in decaying homogeneous isotropic turbulence (DHIT), direct numerical simulations were carried out for DHIT with and without polymers.

Clustering and preferential concentration of finite-size particles in forced homogeneous-isotropic turbulence [PDF]
Journal of Fluid Mechanics, 2016 We have performed interface-resolved direct numerical simulations of forced homogeneous-isotropic turbulence in a dilute suspension of spherical particles in the Reynolds number range $Re_{\unicode[STIX]{x1D706}}=115{-}140$ .
