ASCE has honored Bruno Brunone, Ph.D., M.ASCE, with the 2018 J.C. Stevens Award for his discussion of “Hydraulic Transients in Viscoelastic Branches Pipelines,” Journal of Hydraulic Engineering, August 2016.
Brunone has provided a concise but technically strong discussion on the topic of transient behavior in complex pipe systems as presented by Stefania Evangelista, Angelo Leopardi, Roberto Pignatelli, and Giovanni de Marinis. The discussion is done in a professional manner and is based on technical merit. It recognizes the strengths of the original paper but highlights the difficulties in measuring what is theoretically needed and what is actually feasible. Measuring the pressure wave interacting with the pipe junction should be done at an “infinitesimal” distance. Friction losses and viscoelasticity dampen the pressure wave traveling from the maneuver valve toward the junction and vice versa, causing a difference in the wave generated by the maneuver. Brunone further offers a suggestion from other studies to evaluate the dampening experimentally.
The J.C. Stevens Award recognizes excellence in a paper published by the Society. The paper is in the field of hydraulics, including fluid mechanics and hydrology.
