| Abstract: | Applying NX THERMAL/FLOW to the FEM calculation and analysis of the front diversion body,which is one of the key parts of the turbine flowmeter,we can draw a conclusion that the big vortex trail area caused by flow separation easily appears in the tail of the front diversion body and the shape of vane produces great effect on the change of flow velocity.It provides theoretical basis for the designs of the turbine flowmeter and the front diversion body. |
