This was achieved by supplying a gas mixture of CO2 and air (Aalborg GF17 mass flow controller) to the diffuser within the fish chamber, and recirculating the water exiting the chamber via a 100 l reservoir (which was also aerated with the same gas mixture). This high environmental CO2 ...
Improvement of sound diffusion in a reverberation room at low frequencies The diffuser should be as large as the room dimension permit to reflect the low frequency waves and it should not be of lightweight construction. A ... PN Liang - National Conference on Noise Control Engineering: Bellevue...
diffuser plate 61, a light collecting prism or reflector device 62 and an aperture slit plate 63, on one side of the flow tube 56. Opposing this combination is another aperture slit plate 64, a light collector prism or reflector 65 and a response means in the form of photocell strip 59...
Air flow inlets to industrial devices, such as e.g. Gas turbine compressors include a trumpet-shaped inflow nozzle component that acts to trap an airflow, initially compress and, e.g. in the direction of a turbine section of the compressor. In many devices, the static pressure in the trum...
9. Apparatus as claimed in claim 1, including a diffuser associated with the illuminating means, for diffusing the light emitted by the illuminating means within the internal lumen. 10. Apparatus as claimed in claim 1 or claim 6, wherein the viewing means comprises a light sensitive detector...
One followed the traditional method for collecting full-sky UVR irradiance by using an instrument with a zenith-facing sensor equipped with a diffuser that provides a near-cosine response to global UVR irradiance. The second approach was to measure the UVI with sensors at the eyes, ears and ...
Temperature-controlled air was passed through the diffuser. When the injected microbubbles rise through a thin layer of liquid mixture, they become enriched with the more volatile component within a very short contact time, on the order of a few milliseconds. This means that air leaving the ...
However, as a result of using a fast PSP we can conclude that the pressure distribution is independent of the blade position inside the compressor and not significantly affected by e.g., the diffuser tongue. Using a slow PSP with a response time in the order of seconds the pressure shown ...
