Dual-sensor miniature wire 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. All X-probes measure two velocity components simultaneously in turbulent, stationary two-dimensional flow fields. They provide information for the calculation of Reynolds shear stress. The flow vector may not exceed ±45°. The picture to the right shows the probe dimensions common for dual-sensor miniature wire probes.
