| 摘 要： | 建立了V锥流量计三维流动物理模型和数学模型.借助FLUENT软件分别对不同等效直径比、前锥角、后锥角的V锥流量计的流场分布进行数值计算.分析了不同雷诺数与流出系数的关系.研究表明:前后锥角不变,等效直径比越大,流出系数越小.随着雷诺数的增大.流出系数增值幅度减小并逐渐趋于某一常数.保持等效直径比不变,改变前后锥角,发现...

| Abstract: | The mathematical and physical models of V-cone flowmeter's three-dimensional flow were built.Flow field distribution of the different equivalent diameter ratio and fore-and-aft cone angle's V-cone flowmetes was numerically computed by means of CFD software FLUENT.The relationship between the different Reynolds number and the discharge coefficient was analyzed.The research shows that if the fore-and-aft cone angle keeps the same value,the equivalent diameter ratio increases while the discharge coefficient de... |
