“…Pedagogical treatments in the literature appear to focus primarily on lower level courses in science and engineering. There is little discussion about the teaching and learning of more advanced topics like fluid dynamics [32]. We believe that examples like the ones presented here add value to the science of fluid dynamics in some capacity, but also to the ways in which students can engage with difficult topics in fluid dynamics.…”

We examine two dimensional properties of vortex shedding past elliptical cylinders through numerical simulations. Specifically, we investigate the vortex formation length in the Reynolds number regime 10 to 100 for elliptical bodies of aspect ratio in the range 0.4 to 1.4. Our computations reveal that in the steady flow regime, the change in the vortex length follows a linear profile with respect to the Reynolds number, while in the unsteady regime, the time averaged vortex length decreases in an exponential manner with increasing Reynolds number. The transition in profile is used to identify the critical Reynolds number which marks the bifurcation of the Karman vortex from steady symmetric to the unsteady, asymmetric configuration. Additionally, relationships between the vortex length and aspect ratio are also explored. The work presented here is an example of a module that can be used in a project based learning course on computational fluid dynamics.

Over the last few decades, environmental considerations have become increasingly important in architecture. To predict and simulate material changes and environmental forces can help architects to articulate surfaces. In architectural education, an increasing amount of the curricula are engaging with aspects of energy design, sustainability, and environmental simulations. The successful integration of related novel technologies in education has been demonstrated in the past. This paper documents a technical seminar that focused on the combination of digital environmental simulations and smart materials to create chromogenic prototypes for environmentally responsive architectural composites. Thermochromic chromogenics are substances that reversibly change colour depending on temperature. Specifically, the task was to come up with novel techniques to combine such materials with varying substrates to achieve dynamic panels. The course design was informed by a variety of design research and learning concepts. Students were asked to use digital heat transfer simulations to predict the smart material changes of computationally designed panels. Each of the eight idiosyncratic prototypes was modified with a variety of techniques and coated with thermochromic ink to achieve complex heat signature patterns. The resulting chromogenic composites were documented and analyzed using photos and infrared thermography. The seminar's results showed that the three aspects (simulation, material, fabrication) can help to introduce eco-relevant technologies to design education. For this paper, both the outcomes and the course design itself were reviewed to better understand the co-creation process of the three aspects. This evaluation provided a rich repertoire of possibilities to combine different technologies for creative environmental design in architecture; all while maintaining an engaging teaching environment.

“…A student when opts to study any of the Engineering branch, a student studies Physics along with the Mathematical concepts and Mathematics along with the Physical Science concepts (Ashwin Vaidya, 2020). This is an argument that no student can while away Physics and Mathematics for their semesters.…”

In this paper we will deal about the importance of the study of the subject Fluid Dynamics in Engineering field. Students are more likely to study Engineering courses in the recent days. Engineering deals with the basic concepts of Mathematics, Physics and Chemistry. Though, Computer Science subject is a pulse to Engineering, the subjects, Mathematics, Physics and Chemistry are heart beat to Engineering courses. In this study, we will discuss where and how Fluid Dynamics stands as a crown to Engineering Field.
