Micro-Velocimeter For An Open Channel Flow: A Simple And Economical Alternative
chilean conference on electrical electronics engineering information and communication technologies(2019)
摘要
Research related to hydraulic engineering requires microscale experiments to replicate various phenomena under dynamic conditions. An open channel flow, or also called micro-canal is used to study river floods, scour around coast structures and bridge piers scour. The need for multiple measurement water speed points, in such a way that specific sections of the micro-canal could be controlled, motivated this research. However, the acquisition of high-end speed sensors involves high economic costs being difficult to implement. As a solution, we designed and implemented a micro-velocimeter (MSV) whose operation principle is based on the operation of a small D.C. motor in generator mode. The D.C. generator shaft is turned by a small propeller, which rotates according to the water speed inside the micro-canal. The prototype was designed using AUTOCAD software, simulated by SolidWorks software and built by 3D printing.For the implementation, the MSV was calibrated using an available Acoustic-Doppler Velocimeter (ADV). The MSV is a good alternative for realizing multi-point measurements along of a micro-canal or with a matrix arranged in a specific section or both, in a simple and economical form.
