Zeitaufgelöstes PIV-System


*Diese Seite ist leider nur in Englisch verfügbar.*

TSI can supply integrated PIV systems capable of obtaining data at rates ranging up to 10s of kilohertz. TSI offers "time-resolved" versions of all of our global imaging systems including 2D-PIV, Stereoscopic PIV, V3V™ Volumetric PIV, GSV, SSA, and PLIF. The detailed temporal data obtained from these high repetition rate measurements offer unique information about flow dynamics, flow transport and the motion of structures in a flow.


TSI PIV systems can provide flow field information with very high spatial resolution by making use of high megapixel cameras. Historically, however, the temporal resolution of successive PIV vector fields has been limited by the system’s overall repetition rate, which is governed by the camera frame rate and the laser pulse rate. For most practical flow field applications (in both air and water cases), the system repetition rate has been too low to be of value.

However, the ability to measure flow field evolution as a function of time has always been of great interest to experimentalists. As laser and camera technology progress, we are continually expanding the range of PIV systems in terms of both spatial and temporal resolution (which are often in conflict with each other).

Today, TSI is proud to be able to offer PIV systems capable of operation across a very broad spectrum of repetition rates. TSI offers traditional low-speed (1-15 Hz), mid-speed (~90 Hz), and high-speed systems. Recently, TSI systems have even been able to reach repetition rates in the 10’s of kilohertz range, with pulse energies as high as 50 mJ/pulse.
