建筑排水三通入流角度对流态影响的数值模拟

摘要

In this paper, numerical simulation of the flow state affected by inflow angle in the tee coupling tube was carried out by the Flu-ent software.The standard K-epsilon double equation model was adopted to analyze the flow state in the T tee, 30°oblique tee, 45°ob-lique tee and 60°oblique tee.The simulation results show that the flow state in the tee coupling tube can be improved and drainage is smoother as the inflow angle increases.%本文采用数值模拟的方法，针对建筑排水三通入流角度的改变对流态的影响进行初步研究。数值模拟运用FLU-ENT软件，采用标准k－ε湍流模型，分析T型三通管（0°）、30°斜三通管、45°斜三通管及60°斜三通管内部流态，进而得知，增大建筑排水三通入流角度有助于改善管件内部的水流状态，使得排水更加顺畅。
