FRAP Pro is Vectoflow’s transient flow probes that combine the robustness of pressure probes (e.g. 5-hole probes) with a high temporal resolution of the pressure signal. Depending on the probe geometry, frequencies in the kHz range can also be measured.
Vectoflow's transient probes enable the capture of high-frequency flow phenomena in the kHz range, covering all measurement parameters typically assessed by conventional multi-hole probes: velocities, flow angles, total and static pressure, Mach number, and density. Achieving this high temporal resolution requires positioning pressure sensors as close as possible to the probe head to minimize modulation of pressure fluctuations in amplitude and phase. Vectoflow conducts experimental modulation determinations using a specially developed frequency calibration test bench to ensure accuracy.
Transient probes benefit from the same advantages as stationary probe hardware, including high geometric flexibility and enhanced robustness, facilitated by Vectoflow's optimized additive manufacturing process. This process allows for customizable geometry and material combinations, ensuring optimal performance in dynamic flow environments. Vectoflow offers comprehensive solutions for measuring unsteady flow phenomena, including:
It is also possible to synchronize the measurement with several measuring systems or to trigger measurements using a trigger signal.
