Abstract
In the field of aerodynamics, flow measurement is very important. The quality of the flow influences the design and performance of the various aerodynamic components like compressors, wings, high speed train and turbines. More and more research work is available in the field of flow measurement. Many techniques had been developed for measurement of flow like LDV, PIV and Hot wire anemometry. All these techniques are effective but are very costly. In the present work, calibration of five hole pressure probe is carried out. Literature review reveals that the flow measurement by probe is very effective since it can measure flow parameters such as static and stagnation pressure, velocity of fluid stream. In this work, probe is fabricated and then calibrated by using continuous type wind tunnel. The probe is subjected to known flow field for calibration. The velocity of the fluid stream is maintained at 25 m/sec and the probe is calibrated for different yaw and pitch angle. From the graphs obtained for calibration, it had been found that suitable range for yaw and pitch angle is -200 and +200.The calibrated probe can be extensively used for three dimensional flow measurements. It provides good alternative to same costly techniques of flow measurement.
