Dual-sensor fiber-film probes

Dual-sensor probes are designed for use in two-dimensional flows. The sensors are arranged in X-arrays, where they form an angle of 90° with one another. The fiber-film probes are available in four different prong configurations. All X-probes measure two velocity components simultaneously in turbulent, instationary two-dimensional flow fields. They provide information for calculation of Reynolds shear stress. The flow vector may not exceed ±45°. The picture to the right shows the probe dimensions common for the dual-sensor fiber probes.
