A Dynamic Topology Modeling Method in Wind Tunnel Group Based on Adjacency Matrix

The wind tunnel test requires high-pressure air resources and other power guarantees. As a shared competitive power resource, high-pressure air and its delivery pipeline system for the wind tunnel group have the characteristics of multiple wind tunnel test users, complex system structure, dynamic topology change, and fast resource consumption. To avoid the power resource conflict and realize the cost accounting of the wind tunnel group test, a dynamic topology modeling method of high pressure distribution network in wind tunnel group based on adjacency matrix is developed in this paper. By identifying, storing and updating the high-pressure air-resources network topology structure, the method achieves a dynamic logic link between high-pressure air system compressors, valves, storage tanks, tubes, and the safeguarding of wind tunnels. It automatically captures the difference in high-pressure air tank and guaranteed volume of the current wind tunnel test, and based on hydrodynamic static differential-pressure theoretical analysis, the power consumption of high-pressure air resource in current wind tunnel tests can be automatically obtained. The method has solved the problems of accurate topology description of the high-pressure distribution system and measurement of single test consumption and achieves good results.
