Using numerical simulation to optimize the design of gas turbine flowmeter sensor

In order to optimize the structural design of gas turbine flowmeter sensor, numerical simulation of internal flow for gas turbine flowmeter is conducted with computational fluid dynamics method. The computation have been carried with three dimensional modeling, high quality grid resolution, dynamic grid technique and companying with the practical application of specical boundary condition. The detailed information of velocity distribution and meter factor of gas turbine flowmeter are obtained. Compared simulation results to experimental data, the relative errors are within 2.7%.
