流体在弯管内壁面压强分布研究
Study on the pressure of fluid on the surface in elbow pipes
摘要
Abstract
Elbow pipes are critical components of piping system in petroleum industry, chemical industry, navigation industry, aviation industry and nucleus industry. The study on the distribution of di-mensionless pressure of fluid on the surface of the elbow pipes is the premise of quality safety in producing elbow. This paper is based on the dimensional analysis methods. The qualitative conclusions for the 90° elbow pipe are obtained. By means of prediction of the pressure distribution, the effect of a number of dimensionless parameters such as the non-dimensional curvature, Reynolds number, di-mensionless axial angle α, and annular angle β on the spatial distribution of pressure inside the elbow is analyzed and discussed in detail by numerical method. The results show that the dimensionless pressure decreases on the convex side and increases on the concave side with the bending diameter ratio and that the dimensionless pressure basically has inverse cosine relationship with β.关键词
