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.

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 ...

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 ...

Transient thermal modelling of green anode cooling in the aluminium industry
The Canadian Journal of Chemical Engineering, EarlyView.Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before

Comparison of modelling approaches for liquid fluidized beds
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.

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 ...
