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.
The Space Kid, 11, will be one of the first civilians to have his design manufactured in space by NASA, thanks to the City X Project, which inspires kids to think about new 3D-printed inventions that could be useful for humans living in space.
