Characterization of Pipe-shaped Red Iron Oxide by Annealing Temperature
Funtai oyobi fummatsu yakin, 2016
The purpose of this study was to identify the morphological characteristics and chemical properties of pipe-shaped iron oxide particles depending on the manufacturing method and provide information on possible manufacturing methods and locality survey of the excavated iron oxides. We collected samples around the Toratsuka Tomb and performed firing, followed by optical microscopy, scanning electron microscopy, X-ray fluorescence analyses, and X-ray diffraction analyses. Based on the results, it was demonstrated that the annealing temperature has no effect on the shape of the iron oxide samples while the particle size as well as the color and intensity ratio of iron oxide differed with the annealing temperature. We also obtained information on minor constituents of the iron oxide samples through elemental analyses and gained knowledge on determining the locality by identifying the contained elements.

Flows of nanofluids with rod-like nanoparticles in a microscale channel having cylindrical micro pin heat sinks were numerically simulated to analyze the effect of the aspect ratio of the rod-like particles on the heat transfer and flow in the microscale channel. Furthermore, the optimal aspect ratio was investigated by examining the trade-off relationship between the pressure drop and the thermal efficiency. The Hamilton-Crosser model and Brenner's model were used to describe the thermal conductivity and viscosity of nanofluids, respectively. The numerical simulations revealed that heat flux around the cylinders was more active in the upstream region and increased with increasing the inlet particle volume fraction ϕ in and the particle aspect ratio s and that the effect of the aspect ratio tended to decrease gradually. Furthermore, it was found that the thermal efficiency improved with increasing ϕ in and s but saturated above ϕ in = 0.04 and s = 30, whereas the pressure drop increased further and the increase was more pronounced at large aspect ratios. These results imply that nanofluids with relatively low particle concentration and small particle aspect ratio are suitable as working fluids for heat exchangers.
