Subcritical Contraction For Improved Open-Channel Flow Measurement Accuracy With An Upward-Looking Advm, Daniel Howes, Charles M. Burt, Brett F. Sanders
Subcritical Contraction For Improved Open-Channel Flow Measurement Accuracy With An Upward-Looking Advm, Daniel Howes, Charles M. Burt, Brett F. Sanders
BioResource and Agricultural Engineering
Acoustic Doppler velocity meters (ADVMs) provide an alternative to more traditional flow measurement devices and procedures such as flumes, weirs, and stage rating for irrigation and drainage canals. However, the requirements for correct calibration are extensive and complex. A three-dimensional computational fluid dynamics (CFD) model was used to design a subcritical rapidly varied flow contraction that provides a consistent linear relationship between the upward-looking ADVM sample velocity and the cross-sectional average velocity in order to improve ADVM accuracy without the need for in situ calibration. CFD simulations validated the subcritical contraction in a rectangular and trapezoidal cross section by showing …

Design, Planning, And Evaluation Of Upgraded Cattle Handling Facility, Lindsey Kaeli Tulloch
BioResource and Agricultural Engineering
This senior project discusses the design, planning, and evaluation of a livestock handling facility for Tulloch Ranches. The facility will be an upgrade to the facility currently used at the ranch in Pine Valley, California. The design parameters for the facility were narrowed down to the following: 1. Must reduce stress to animals during handling. 2. Must be cost effective to save labor and maintenance. 3. Must show improvement from the current set- up. The above parameters combine to form a system that enables the handlers of Tulloch Ranches to manage and work cattle in a more calm and humane …
