【 摘 要 】

A calculated and experimental study of the inner tube rotation effect on the pressure drop in the annular channel at the turbulent Newtonian flow was carried out. The Reynolds number varied from 2000 to 24000. The rotational Reynolds number ranged from 0 to 2100. The diameter ratio of the inner and outer pipes of the annular channel ranged from 0.286 to 0.714. Calculation was in good agreement with experiment.
