Biporous media having clusters of size range 300 - 425 μm, 425 - 600 μm, > 600 μm have been sintered at 950 °C, 180 min using gas atomized spherical particles (D50 of 90 microns) of pure copper in reducing atmosphere of pure hydrogen gas. MicroCT scan of biporous samples have been performed to and then images have been reconstructed to 3D CAD models, which further have been discretised into tetrahedral mesh using image processing and reconstruction software Avizo Fire 8.0. Direct numerical simulations have been performed to obtain Evaporative heat transfer coefficient (EHTC) over the surface of these biporous clusters. The transient evaporation phenomena and effect of cluster size on evaporation has been investigated in this paper. These results have been compared with the experimental results available in literature for evaporative heat transfer coefficient for biporous media.
