Abstract
Provided herein are components for a fluid network, specifically a U bend structure connected to at least two pipes which is modified for one or more objective functions of interest such as pressure drop, erosion rate, fouling, coke deposition and operating costs. The U bend structure is so designed to have a specific ARQ between 1.0 to 1.02 for 5% of the flow passage from the inlet and from the outlet, and an ARQ from 1.02 to 1.15 over the remaining 90% of the flow passage through an Rb/D ratio being greater than 1 and less than 4.
