双锥流量计流出系数特性的数值模拟与试验研究
Computational simulation and experimental research on the discharge coefficient of double-cones flowmeter
摘要
Abstract
The double-cones flowmeter. a new type of differential pressure flowmeter, is introduced. The study combines simulation using Fluent software with experiments to explore the influence of the Reynolds number and diameter ratios j3 to the rule of double-cones discharge coefficient. Six flowmeters with different beta ratios for 50mm pipe diameter are machined. Through the processing of numerical data, it is found that the discharge coefficient is related with the Reynolds number and within a certain range it's going to a constant. Besides, the beta ratios have little influence on the discharge coefficient and on the condition of certain error permission, the discharge coefficient of double-cones flowmeter is nearly not relevant to the beta ratios. What's more, all the simulation results are validated by experiments and the error of simulation is less than 3%.关键词
