摘　　要：为了深入研究涡轮流量计的工作原理,以改善其精度,通过计算流体力学的方法对100 mm口径的气体涡轮流量计进行了数值模拟,给出了气体涡轮流量计的速度场、压力场、速度矢量场及其压损。研究了不同流量下的压损值,并通过实验进行了比较,结果表明数值仿真与实验结果基本吻合。In order to study the operation principle about the turbine flow-meter to improve its accuracy,numerical simulation of internal flow for DN-100 gas turbine flow-meter is conducted with computational fluid dynamics method,and the detailed information of pressure loss,velocity vector,speed vector and pressure distribution of gas turbine flow-meter are obtained.The pressure loss is studied under different flow rate,and is compared with the experimental result.The result shows the simulation result is basically similar with the experimental result.
