回転振動を伴う加熱円管周りの流れと伝熱特性に関する数値解析

Numerical simulations were conducted by using OpenFOAM to investigate the flow and heat transfer characteristics around a heating cylinder with rotational vibration. In a previous study, it was reported that the drag force of a rotating oscillating cylinder was lower than that of a stationary cylinder. Therefore, it is expected that the application of rotational vibration to a heated circular tube can expand the dissimilarity between momentum and heat transport and lead to higher efficiency of heat exchangers. In this study, numerical simulations were conducted to clarify the effects of Reynolds number Re, rotational speed ratio V_r, and forced Strouhal number S_f on flow resistance and heat transfer characteristics.
