Abstract

This paper describes numerical and experimental investigations on internal standing waves occurring in a cylindrical vessel and their near-wall behavior in the vicinity of an adiabatic cylinder located at the center of the vessel. A numerical prediction method was developed with a low-Reynolds-number turbulence model to stimulate the occurrence of the internal standing waves and their near-wall features. These features are characterized by the attenuation and phase shifts in temperature fluctuations as observed in the present experiments. The measured results were well predicted by the numerical simulation in terms of certain statistical values as well as qualitative internal wave motions and flow patterns.
