Design of Gas Flow Metrology Virtual Simulation Experiment Project
The gas flow standard device is expensive and has a complex structure,which is difficult for students to operate in traditional experimental teaching.Hence,a virtual simulation experiment project of gas flow metrology is developed.The transmission standard of gas flow capacity of sonic nozzle flow standard is developed based on virtual simulation technology.Through the virtual three-dimensional scene,students can have a comprehensive understanding of the structure and working principle of gas flow devices,and master the quantity transferring and traceability methods of gas flow.Meanwhile,the interactive steps for gas turbine flowmeter calibration are designed based on the verification regulation,which helps students to master the calibration process and measurement performance evaluation methods of turbine flow meter.The difficulties encountered in traditional experimental teaching of flow metrology are well overcome,which achieves good experimental teaching effects.Moreover,the students'major recognition and professional ability are improved effectively by the project.
