概要
- 論文の詳細を見る
The experimental results of pressure distribution and velocity profile of diverging and converging flows are obtained. The results of dilute polymer solutions are compared with those of Newtonian fluids. In a converging flow, a remarkable drag reduction such as a pipe flow is not recognized. In a diverging flow, when α=5° and the concentration becomes 60 ppm, pressure recovery represents a value about 30% larger than Newtonian fluids. The logarithmic velocity distribution are shifted upwards from the law of the wall due to the influence of both the pressure gradient and polymer additives.
