ふく射加熱を受ける多孔質体を挿入した流路の熱流動解析

抄録

This study focused on porous-inserted channel with radiative heating. A cubic lattice structure is assumed as an elementary porous structure. Open-source CFD code “OpenFOAM” was used to calculate conductive heat transfer in the solid region and heat transfer between fluid and solid region, simultaneously. Heat transfer medium is air. Flow is assumed as laminar flow, thus Reynolds number varied from 12.6 to 474. Otherwise, optical parameters (e.g., extinction coefficient and scattering phase function) were derived from the Monte Carlo ray-tracing technique. The calculated local radiative heat flux distribution was incorporated into the fluid analysis, and the heat transfer by radiation, convection, and conduction was investigated.
