1838 Study on the Rectifying Device using Octahedral Blocks
Details
A new rectifying device is developed that is constructed of octahedral blocks and has a low-pressure loss. The device consists of octahedral blocks and support struts. Experiments are conducted to test the airflow in a nozzle that has this new device in it. The downstream velocity profile is measured using a Pitot tube and a hot-wire anemometer. The experimental results show that the velocity profiles downstream of the rectifier that consist of octahedral blocks are better in uniformity compared to ones with a wire-mesh (8 mesh). The pressure loss coefficient of the new device is about 40% lower than the one with the wire-mesh. Thus, the new device is proven to be a useful rectifier.
