A novel CFD algorithm called LEAP is currently being developed by the Kasbaoui Research Group (KRG) using the Immersed Boundary Method (IBM) to describe complex geometries. To validate the algorithm, this research project focused on testing the algorithm in three dimensions by simulating a sphere placed in a moving fluid. The simulation results were compared against the experimentally derived Schiller-Naumann Correlation. Over the course of 36 trials, various spatial and temporal resolutions were tested at specific Reynolds numbers between 10 and 300. It was observed that numerical errors decreased with increasing spatial and temporal resolution. This result was expected as increased resolution should give results closer to experimental values. Having shown the accuracy and robustness of this method, KRG will continue to develop this algorithm to explore more complex geometries such as aircraft engines or human lungs.
0° spoilers reduced the wake area behind the car, decreasing pressure drag but also decreasing underbody flow, causing a reduction in drag and downforce. Angled spoilers increased the wake area behind the car, increasing pressure drag but also increasing underbody flow, causing an increase in drag and downforce. Longer spoilers increased these effects compared to shorter spoilers, and short spoilers at different angles did not create significantly different effects. 0° spoilers would be best suited for cases that prioritize fuel economy or straight-line acceleration and speed due to the drag reduction, while angled spoilers would be best suited for cars requiring downforce. The angle and length of spoiler would depend on the downforce needed, which is dependent on the track.
The goal of themed entertainment is to use activities and environments to tell a story and immerse the guest in a novel experience. By applying these concepts to nonfiction and educational topics, the concept of edutainment is created. In recent years museums have begun utilizing the concept of edutainment and techniques typically found in themed entertainment experiences to capture the attention and focus of guests and create experiences that connect emotionally with them. My goal in this thesis pathway project was to investigate this trend and technique of connecting with an audience and apply it to the STEAMtank project within ASU’s Innovation Space. The goal of STEAMtank is to design and fabricate children’s STEAM museum exhibits in two semesters with focus on accessible design. My team conducted research and interviews exploring current market trends in theme parks and museums, best practice designs and operations, and interests of children to develop the concept for our exhibit, Gust of Dust, which was then fine-tuned, constructed, and installed in the STEAMtank Exhibit Space. Gust of Dust is an exciting exhibit demonstrating the power of a haboob that was developed from preconcept to installation in under a year by two determined and talented interdisciplinary teams. Learning about haboobs connect concepts of environmentalism, earth science, and safety to real concepts in children’s lives.
