Fully automatic collection of three-dimensional flow field data between cascade levels, Windtuner Technology can also provide aerodynamic probe Ma: 0.2, 0.4, 0.6, 0.8 calibration and other services. In practice, when the aerodynamic probe is used to measure the flow field of the cascade, especially in the turbomachinery, the change of the attack angle of the turbine cascade will greatly disturb the flow field of the cascade, which will directly lead to a huge change in the aerodynamic performance of the turbine cascade, resulting in the data measured by the aerodynamic probe deviating from the reality. When the positive attack angle increases, the secondary flow intensity at the cascade outlet increases significantly; When the negative angle of attack increases, the secondary flow intensity decreases continuously. In the case of large negative angle of attack, the secondary flow loss is mainly caused by the friction loss in the end wall boundary layer. When the turbine cascade inlet angle of attack changes from a large negative angle of attack to a positive angle of attack during the test process, the blade profile loss and secondary flow loss both decrease first and then increase. Under the condition of negative angle of attack, the variation range of turbine losses is small, especially the variation of secondary flow losses is extremely weak; When the inlet angle of attack is positive, the turbine losses will increase rapidly with the increase of the positive angle of attack. Pneumatic probes can accurately measure changes in speed in all directions during this complex process, combined with the use of devices such as Ethernet Intelligent Pressure Scanners. High-performance customized pneumatic probes can help solve many test problems.
Moreover, the intelligent Ethernet Intelligent Pressure Scanners system currently launched by Windtuner can be adapted to PSI9216 or DSA3217 Ethernet Intelligent Pressure Scanners without changing the original software. The corresponding communication module can directly match the communication connection with different brands of Ethernet Intelligent Pressure Scanners, which greatly saves the cost of scientific research. Customers do not need to reduce the original configuration, but can increase the configuration of new products.
WindLabX series measurement and control software used by Windtuner in three-dimensional flow field measurement and control adopts LabVIEW visual programming method, and has a variety of functional modules. The basic functions include equipment management data acquisition, storage and viewing, parameter setting, etc., with high test accuracy, fast response speed, At the same time, it also supports the networking of multiple devices to form a distributed data acquisition system. At the same time, like Ethernet Intelligent Pressure Scanners, it also supports the adaptation of PSI9216 or DSA3217 Ethernet Intelligent Pressure Scanners and ConST811A/ConST820 intelligent all-round automatic pressure calibrator and other equipment.
