초록

An experimental study was undertaken to investigate the effect of coriolis force for the turbulent flow at low Reynolds numbers in a rotating straight square duct. The study was carried out using a hot-wire anemometer. The flow Reynolds number based on the hydraulic diameter ranged from 4,000 to 18,000 and Rotation number ranged from 0 to 0.196. At Re=9000, developing turbulent flow was calculated for mean velocity and Reynolds stress. Pressure coefficient and energy dissipation spectrum were also calculated.
