摘要
针对87型屋面雨水排水系统基于重力流设计但实际运行中可能存在半有压流态的特点,结合相关厂家的水力实测试验成果,引入数值模拟技术,分析各种降雨强度下87型雨水系统的排水性能,对比研究其水力工况(斗前水深、气水两相流流态、排水量),为工程应用提供参考依据。
Although the 87 type rainwater hopper rainwater drainage system is based on the gravity water flow,there is still half-pressured water flow in the rainwater drainage system with 87 type rainwater hopper.Based on this fact and the hydraulic test results from producer,the numerical simulation was used to analyze the drainage performance of the 87 type rainwater hopper under various rainwater intensities.In addition,a comparison study was carried out to study its hydraulic working condition including water depth before rainwater hopper,gas-water two-phase flow and discharge capacity.This paper might be reference for engineering application.
