Abstract: AbstractDetailed turbulent flow profiles have been measured on a square sub-channel geometry with typical mixing devices. For a fine examination of the lateral flow structure on a sub-channel geometry with 2-D LDA, a 5x5 rod bundle array was fabricated as 2.6 times larger than the real bundle size. The mixing devices used were a typical split type and a swirl type. The experiments were performed at the condition of Re=50,000 (axial bulk velocity 1.5 m/s) and the water loop was maintained at the conditions of …
