Abstract

In two-dimensional flow measurement using Hot wire anemometer, Directional sensitivity (angular response) of sensor plays an important role in the measurement accuracy. The angular response of the sensor describes the relationship between flow velocity vector and heat transfer from the sensor, which is determined by a sensitivity function. In this paper, two sensitivity functions, namely Cosine law and Hinze equation, have been studied using wind tunnel experiments to evaluate the effect of various parameters such as flow conditions (velocity and direction), Probe aspect ratio (l/d) and probe operational condition (sensor temperature) on the range of applicability of Cosine law and magnitude of the Sensitivity coefficient, k. Results show that the angular range of applicability of Cosine law depends on flow and probe conditions. At 1% measurement error, the range of applicability of Cosine law for flow measurements of velocities exceeding 10 m/s was found to be in the range of ± 30º . Moreover, at geometrical ratios higher than 600, two-dimensional flow measurements using the Cosine law presents results with acceptable accuracy. In addition, the Sensitivity coefficient is completely dependent on flow condition and Probe aspect ratio, and its value decreases with increase in flow angle and velocity and reduction in Probe aspect ratio. The results of this research can be used in the selection and proper design of probes for two-dimensional flow measurements using Hot wire anemometers.
