This work deals with an experimental procedure to validate theoretical equations used for pressure losses inside anemometer testing equipment. This equipment allows for the generation of air flow inside a chamber designed for anemometer calibration testing at different air speeds. To calibrate anemometers to high accuracy, the air flow must have very low turbulence and uniform velocities over the testing chamber cross section. For high performance, the anemometer testing equipment used a closed-circuit wind tunnel design.In designing the anemometer testing equipment, the pressure losses of single components were evaluated as well as overall pressure loss utilizing theoretical equations found in the scientific literature. Once the pressure losses were evaluated, the fan was chosen to ensure volumetric flow, balance pressure losses and above all maximise its performance.With the design completed, the anemometer testing equipment was built, and a campaign of experimental measurements was performed to evaluate the accuracy of the theoretical pressure loss equations. The campaign was performed in two different conditions: closed testing chamber and open testing chamber. The results showed good agreement between the theoretical and experimental pressure losses for the closed testing chamber. Conversely, a discrepancy was revealed for the open condition. The origin of this discrepancy was investigated and a new equation proposed. 相似文献

Two torispherical drumheads which had previously been used for shakedown testing, have been used to determine the effect of proof testing. One drumhead was pressure cycled at its design pressure prior to undergoing a proof test and subsequent pressure cycling. The second drumhead was subjected to a proof test and subsequently pressure cycled at its design pressure. For the first drumhead, significant incremental strain was evident prior to the proof test but not after the proof test. For the second drumhead, no incremental strain was evident after the proof test. 相似文献

In the event of a fire, composite pressure vessels behave very differently from metallic ones: the material is degraded, potentially leading to a burst without significant pressure increase. Hence, such objects are, when necessary, protected from fire by using thermally-activated devices (TPRD), and standards require testing cylinder and TPRD together. The pre-normative research project FireComp aimed at understanding better the conditions which may lead to burst, through testing and simulation, and proposed an alternative way of assessing the fire performance of composite cylinders. This approach is currently used by Air Liquide for the safety of composite bundles carrying large amounts of hydrogen gas. 相似文献
