Fluid-flow and endwall heat-transfer characteristics of an ultralight lattice-frame material

Permeability measurements and modeling of topology-optimized metallic 3-D woven lattices

“…The resulting relationships between normalized permeabilities (K/D h 2 ) and material volume fraction (V f ) are plotted in Fig. 10 for the standard and optimized 3-D woven structures (X-direction permeability shown), stochastic metallic foams [1,2,[58][59][60] and other periodic cellular media [7,16,56,61] including square, diamond and truss structures.…”

“…10 they offer more than a 10-fold increase in normalized permeability compared to foams with a similar volume fraction. Other periodic cellular materials, such as square, diamond and truss structures, [7,16,56,61], have similar normalized permeabilities, but their material densities tend to be much lower. The comparisons in Fig.…”

Fluid dynamics of flow through microscale lattice structures formed from self‐propagating photopolymer waveguides

“…Numerous previous studies characterizing fluid flow through microchannels 42 and macroscale lattice frame materials [43][44][45] are examined. However, the unit cell size, periodic arrangement, porosity and flow angle dependence of the presented microscale lattice structure are unique compared to previous microscale studies.…”

“…7). In many flow conditions, the pressure loss is largely independent of the truss material used 43 ; therefore, Eqs. 6 and 7 should apply not only to the polymer microscale lattice structures tested but also to ceramic or metal forms fabricated using the original polymer truss structures as templates.…”

Forced convection in metallic honeycomb structures

“…Comparisons between the overall thermal performances of metal honeycomb structures and selected heat sink media, including metal foams [23][24][25][26][27][28][29], lattice-frame materials [30][31][32][33], Kagome structures [34], and woven textile structures [35,36], are presented in Fig. 9.…”
