“Designing and controlling open channel flows presents many challenges. One such challenge is energy dissipation. This challenge is currently addressed by several means, including the use of honeycomb structures. Energy dissipation by honeycomb structures has been studied for pressurized conduit flows; however, their ability to dissipate energy in free-surface flows remains largely unexamined. This work introduces a comprehensive experimental study designed to estimate the energy dissipation through a honeycomb structure in a free-surface flow.
This work examined the energy dissipation for a range of flows, pipe lengths, and pipe diameters in two flumes. PVC pipes ranging from 6 inches to 2 feet in length and from . inch to 2 inches in diameter were used to build honeycomb structures. These structures were subjected to a range of flows between 0.053 cubic feet per second (cfs) and 4.310 cfs.
A non-linear regression analysis was conducted using SPSS software on the measured data to obtain an empirical dimensionless equation. This empirical equation represents the head losses as a function of discharge and geometric parameters. The parameters in the empirical equation were examined by a sensitivity analysis to determine which parameters are most influential. The results of this work showed that head losses are correlated negatively with the pipe diameter, and positively with the discharge and pipe length”--Abstract, page iii.
