Five Hole Fast Response Probe for Measurements of 3D Velocity and Pressure Fields
Апстракт
In this paper is presented the Fast Response Aerodynamic Probe (FRAP), for measurements of the nonstationary fluid flow, widely present in the energy systems. Multihole probes are well known in experimental fluid mechanics. This is, on the contrary to the optical velocity measurement techniques, intrusive anemometry and pressure measuring device. It is, recently, updated with fast response sensors, which enable good sampling rate, necessary for turbulence study.
Calibrations, aerodynamic, as well as dynamic one, and working principles of the FRAP probe are introduced. Probe design and implemented sensors are presented and described in numerous details.
Design of the test rig for necessary pitch-yaw aerodynamic calibration is developed and it is planned to achieve automated calibration procedure.
Results of the dynamic/acoustic calibration reveal fast probes response, up to 10 kHz.In addition, results of the first aerodynamic calibration for one velocity are presented and discussed.... Obtained map of the calibration angles is provided, as well as diagrams of two out of five measured pressures. Determined velocity is, also, presented and analyzed error.
