Solution are obtained for Dean number to 550 correctly by using the power-law scheme and it can be calculated to the Dean number to 900 by using the up-wind scheme. The results are compared with the available experimental and the theoretical results. It was found that the friction factor became larger about 6% when the flow changed from the two vortex to the four vortex flow patterns, which occurred the Dean number was 116.0. The slope of the friction factor was different between the two vortex and the four vortex regions. Our results showed better agreement with the experimental results than the other theoretical results., 資料番号: NALSP0010018, レポート番号: NAL SP-10}, title = {矩形曲り管内の流れと熱伝達}, year = {1989} }
