Contribution of vortex structures and flow separation to local and overall pressure and heat transfer characteristics in an ultralightweight lattice material

Convective heat transfer and pressure losses across novel heat sinks fabricated by Selective Laser Melting

“…The high thermal conductivity of the metal combined with the eddies generated within the foam act to provide about five times the heat transfer when compared to a pin fin array, but with the added penalty of high pressure drop. Lattice type materials consisting of angled cylinders were investigated by Kim et al [20][21][22] for applications where heat sinks are also required to carry structural loads; their performance was found to be similar to that of a bank of cylinders.…”

Fabrication and heat transfer characteristics of C/SiC pyramidal core lattice sandwich panel

“…Various reports have studied the forced convection in the lattice core sandwich panels [24,25]. However, due to the complexity of the core geometry, the heat transfer mechanism of the lattice panel has never been reported till now.…”

The fabrication and surface functionalization of porous metal frameworks – a review

“…These periodically structured materials composed of stacked metal meshes or foams, must present well-ordered morphologies with low porosity and large interconnected through pores in order to act as efficient heat sinks 21,248 . In addition to their morphology, these materials must also offer high thermal conductivity and diffusivity 16,247,249,250 . The thermal and fluid flow characteristics of such woven metal textiles were comparable to plate-fin heat exchangers while being up to 40 % lighter.…”
