静压复得等静压送风管在工程上具有广泛应用,但至今尚缺乏一个比较完善的数学模型。本文运用流体力学的基本知识,在静压复得原理基础上,建立起等静压送风管基本几何形状的数学模型,从而得出基本理论曲线,以及影响该曲线形状的主要物理和几何参数。为工程设计提供了理论参考。本文还从实践出发,分析了在大型高速电子计算机通风系统中,采用静压复得等静压送风管的工程应用价值,及目前存在的主要问题。
Hydrostatic pressure isobaric duct has a wide range of engineering applications, but so far there is still a lack of a more comprehensive mathematical model. Based on the basic knowledge of fluid mechanics, based on the principle of hydrostatic recovery, a mathematical model of the basic geometry of isotropic air ducts is established, and the basic theoretical curves and the main physical and geometrical parameters that influence the shape of the curves . For engineering design provides a theoretical reference. Based on the practice, this paper also analyzes the engineering application value of static pressure air supply pipe in large-scale high-speed electronic computer ventilation system, and the main problems at present.
