It uses a mico-structured cantilever with a specifically designed tip as a sensing element and is capable of performing measure- ments with extremely high temporal (≈ 100kHz) and spatial (≈ 140μm) resolutions. Another big feature is a large angular range of 180◦ in total. The performance of the 2d-LCA has been verified by means of comparative measurements with commercial x-wires in laboratory-generated turbulent flow. We are able to show that both measurement techniques provide comparable statistics. |
