摘　　要：应用专业流体分析软件CFX对蝶阀中的流体进行了三维模拟分析,并在阀盘处于不同的开启度(即阀盘的开启角度)下,研究了阀门的流动特性如流量系数、水力扭矩系数、空化系数等。通过经验值和模拟值的比较,验证了计算机模拟研究的有效性。Three-dimensional numerical simulations by commercial code CFX were conducted to observe the flow patterns and to measure valve flow coefficient, hydrodynamic torque coefficient and cavitation coefficient when butterfly valve with various opening degrees and uniform incoming velocity were used in a piping system. By contrast, a group of experimental data is used to compare with the data obtained by CFX simulation to investigate the validity of numerical method.
