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 Vr, and forced Strouhal number Sf on flow resistance and heat transfer characteristics.
