An even distribution of fluid through any cross sectional area of pipe elbows has reportedly been achieved by the Cheng Rotation Vane (CRV)®
by Cheng Fluid Systems (www.chengfluid.com). Key to the accomplishment is the specially designed stationary vanes welded to the inside of a cylindrical body. The completed body assembly is welded or flanged directly to the upstream side of an elbow. Under gas or liquid flow conditions, the incoming fluid is pre-rotated by the stationary CRV vanes. The rotating fluid exiting the CRV has a gyroscopic motion that can counteract the elbow-induced gyroscopic motion.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
