The output characteristics of the averaging Pitot tube flowmeter installed downstream a plane n elbow was studied numerically. A based turbulence model of turbulence iwass appliused to solve the turbulent problem. The control equation iwas discretized with the finite volume method. Three installing styles have been examined,i.e. parallel,vertical and 45°(relatedive to the elbow plane).The output characteristics of the flowmeter was discussed accompany with the flow field data in the pipe and that inside the...
