A robust and intuitive understanding of fluid mechanics-the applied science of fluid motion-is foundational within many engineering disciplines, including aerospace, chemical, civil, mechanical, naval, and ocean engineering. In-depth knowledge of fluid mechanics is critical to safe and economical design of engineering applications employed globally everyday, such as automobiles, aircraft, and sea craft, and to meeting global 21st century engineering challenges, such as developing renewable energy sources, providing access to clean water, managing the environmental nitrogen cycle, and improving urban infrastructure. Despite the fundamental nature of fluid mechanics within the broader undergraduate engineering curriculum, students often characterize courses in fluid mechanics as mathematically onerous, conceptually difficult, and aesthetically uninteresting; anecdotally, undergraduates may choose to opt-out of fluids engineering-related careers based on their early experiences in fluids courses. Therefore, the continued development of new frameworks for engineering instruction in fluid mechanics is needed. Toward that end, this paper introduces mobile instructional particle image velocimetry (mI-PIV), a low-cost, open-source, mobile application-based educational tool under development for smartphones and tablets running Android. The mobile application provides learners with both technological capability and guided instruction that enables them to visualize and experiment with authentic flow fields in real time. The mI-PIV tool is designed to generate interest in and intuition about fluid flow and to improve understanding of mathematical concepts as they relate to fluid mechanics by providing opportunities for fluids-related active engagement and discovery in both formal and informal learning contexts.

In this paper we present a non-intrusive experimental approach for obtaining a two-dimensional velocity distribution around a 22 mm diameter circular cylinder mounted in a water tunnel. Measurements were performed for a constant Reynolds number of 7670 using a commercial standard particle image velocimetry (PIV) system. Different flow patterns generated behind the circular cylinder are discussed. Both instantaneous and time-averaged velocity distributions with corresponding streamlines are obtained. Key concepts in fluid mechanics, such as contra-rotating vortices, von Kármán vortex street, and laminar-turbulent flow, are discussed. In addition, brief historical information pertaining to the development of flow measurement techniques-in particular, PIV-is described.

“…Unsurprisingly, this methodology has also spread into pedagogical contexts, mainly in the form of commercially distributed PIV systems such as FLOWCOACH and ePiv [9][10][11][12][13]. In teaching the subject of PIV in modern education, a thorough presentation of the potential of these systems for senior level mechanical engineering students with pedagogic and economic guidelines related to these systems is provided in [14].…”

“…In summary, the objective of this paper is to present a DIY-PIV system along with enough context on one of its possible particular applications to promote its use as a teaching with technology pedagogical resource on fluid mechanics. This system differs in perspective from, for example [14], in that we do not aim to detail its wide-ranging experimental potential but will instead concentrate on its use as a source of self-contained pedagogical units that can applied (though not exclusively) to the study of oscillatory laminar incompressible flow in narrow channels. As far as we know, this kind of (fluid) flow has not been used in the design of pedagogical resources for physics/engineering education despite its relationship with quite illustrative phenomena in the conceptual framework of fluid mechanics, some of which will be discussed here.…”

A harmonically driven oscillatory fully developed laminar flow through a rectangular cross-sectioned duct is analytically and experimentally studied. Experimental data is gathered at low cost with a relatively easy to implement, non-commercial, do-it-yourself (DIY) particle image velocimetry (PIV) system, which is proposed here as a flexible pedagogic resource for use in physics/engineering fluid mechanics undergraduate or graduate level education. As a DIY system, its components can be generic and/or open source based, making it useful in developing countries as well. An analytical model was developed, solved, and compared to the experimental data while the key features of the oscillatory flow were recognised and reciprocally represented by theory and experiments. This validated the proposed system as a low-cost alternative to the commercially available systems and it also confirmed it as a viable pedagogical resource. Consequently, the activities described could be straightforwardly implemented into undergraduate/graduate fluid mechanics pedagogical contexts, such as lecture aids, course projects, and laboratory practices. The proposed DIY-PIV system constitutes a teaching with technology pedagogical resource on fluid mechanics physics/engineering education that is also able to function as a limited/auxiliary or even state of the art research tool, according to the budget and the objectives.
