Ordinary probes usually refer to single-hole or double-hole probes, which are used to measure single physical quantities in the flow field, such as velocity or pressure. This type of probe is relatively simple in structure, consisting of a slender tube with small holes at one or both ends of the tube, through which the pressure change of the fluid is induced. Ordinary probes are suitable for local parameter measurement under relatively simple flow conditions.
Five-Hole Probe is a more complex porous probe. It arranges five small holes in different directions at the front end of the probe, which can simultaneously collect information such as static and total pressure in multiple directions. This design enables the Five-Hole Probe not only to determine the flow velocity, but also to determine the flow direction, so it has obvious advantages in complex flow analysis.
In addition to structural and functional differences, the Five-Hole Probe also shows significant advantages in accuracy and reliability. Five-Hole Probe usually uses precise manufacturing processes and materials to ensure its measurement accuracy and stability. At the same time, the design of Five-Hole Probe also considers the needs of experimental errors and variants, and improves the accuracy and reliability of data by balancing multiple data points. This makes Five-Hole Probe more reliable and trustworthy in scientific research and industrial applications.
In terms of application, Five-Hole Probe has a wide range of applications. In addition to wind tunnel tests, engine tests, and aircraft tests, Five-Hole Probe can also be used in other situations where accurate measurement of flow field parameters is required. In contrast, the scope of application of ordinary probes is relatively limited, and can usually only be used for some simple measurement tasks.
In addition, the Five-Hole Probe is relatively inexpensive to use. While the initial investment of the Five-Hole Probe may be high, due to its efficient data acquisition capabilities and accuracy, it can significantly experiment and data processing time, and thus overall cost. Although ordinary probes are cheap, due to the limitations of their measurement accuracy and reliability, they may require more experimental and data processing time, resulting in an overall cost.
Which type of probe to choose depends on the specific application requirements. If only a simple and fast flow measurement is required at a fixed location, a normal probe may be a more economical option; But for advanced research that requires a comprehensive understanding of flow field characteristics, Five-Hole Probe undoubtedly provides a more technical solution. Among many brands, WindtunerFive-Hole Probe can be customized for design and production according to customer needs, and also provides services such as pneumatic probe calibration, so as to provide scientific researchers and engineers with more accurate and reliable measurement tools.
