| Abstract: | The computational fluid dynamics(CFD) method was employed to simulate the flow characteristics of a V-cone flow-meter,and the results were compared with the experimental results.The numerical simulation shows that the support inside the V-cone flow-meter could be very influential to the flow field around it,and will bring more error in the measurement.Modification of the support can diminish the disturbances around it,increase the pressure difference between the two pressure probes and thus improve the test... |
