“…Attempts to assemble and test the two turbines into one single hybrid unit have shown promising outcomes [28,29]. In the hydrology area, large size tanks facilitate investigations of particle sedimentation carried by water flow [30], improvement of hyporheic zones due to riverbed restoration [31], and effects of flood waves on river banks [32] among many other studies. The open channel allows examination of flow qualities, such as head loss and turbulence, by placing out obstacles in its test section.…”

“…Lastly, we would like to mention flume experimentations to test the drag and lift of 3D-printed models of swimmers [1] that show the capability of water flume to accommodate large range of multidisciplinary applications. The transparent chamber of the flume certainly allows flow measurement by either direct observation [33,34] or flow visualization technology such as dye injection [31], hydrogen bubble [37], particle image velocimetry (PIV) [23,37,38], planar laser-induced fluorescence (PLIF) [39], stereoscopic digital particle image velocimetry (SDPIV) [40], laser doppler velocimetry (LDV), and acoustic doppler velocimetry (ADV) [30] methods. It is obvious that the versatility and easy-to-maintain characteristic of the open flume systems makes the device very attractive to be included in fluid mechanics and hydrology labs.…”

Open water flume tanks with closed-loop circulation driven by centrifugal pumps are essential for hydro experimentation in academic settings as well as research centers. The device is also attractive due to its versatility and easy-to-maintain characteristics. Nevertheless, commercial open flume systems can be expensive and become less prioritized in engineering schools. This paper describes the design and fabrication of an affordable, medium-size water flume tank, suitable for education purposes. The central piece of the system is a transparent observation chamber where fluid experiments are typically conducted and observed. The expected maximum average water speed in the observation chamber of about 60 cm per second was achieved by the inclusion of a 3 hp centrifugal pump. The size and capacity of the current design were constrained by space limitation and available funds. The educational facility was assigned as a two-semester multi-disciplinary capstone senior design project incorporating students and faculty of mechanical, electrical, and computer engineering programs in our campus. The design process provides a training platform for skills in the area of Computer Aided Designs (CAD), Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), manufacturing, and experimentation. The multi-disciplinary project has contributed to the improvement of soft skills, such as time management, team working, and professional presentation, of the team members. The total material cost of the facility was less than USD 6000, which includes the pump and its variable frequency driver. The project was made possible due to the generous sponsor of the Vibration Institute.
