A new approach to highly resolved measurements of turbulent flow

In this paper we present the design and principle of a new anemometer, namely the 2d-Laser Cantilever Anemometer (2d-LCA), which has been developed for highly resolved flow speed measurements of two components (2d) under laboratory conditions. We will explain the working principle and demonstrate the sensor’s performance by means of comparison measurements of wake turbulence with a commercial X-wire. In the past we have shown that the 2d-LCA is capable of being applied in liquid and particle-laden domains, but we also believe that other challenging areas of operation such as near-wall flows can become accessible.

Development of Highly Resolving Drag Based Anemometers

This contribution presents two new drag based anemometers for highly resolved atmospheric flow measurements. Although both sensors are based on the same measuring principle, they are designed to meet significantly different requirements. The 2D Laser-Cantilever-Anemometer is intended for small scale velocity and direction investigations with frequencies in the order of several kHz. The sphere anemometer is designed to be a robust and higher resolving alternative to commonly used sensors in wind energy such as cup anemometers.
