Vortex Dome STEM Desk Toy - Handmade in the UK by David Fowler

Product Information

By the way guys, we love fan-art! So if anyone wants to get their work displayed on our blog, make something nice and tell us about it! Lee, J.H.; Kim, Y.C.; Cheon, D.J.; Yoon, S.W.

Optimised for a range of applications with RGBW, a wide CCT range and high speed modes for shooting up to 5000fps.

This is a beautiful physics toy designed for your desk. A vortex lives in here, just spin the gorgeous glass dome to see it. You simply spin the glass dome one way or the other and watch the rheoscopic fluid swirl fascinatingly inside. Be careful because it will hypnotize you! DrakeElvin - Programmer / Companion Creator. Created the Kate companion and handled most of her programming. Also programmed the basic companion functions that Deadpan was built upon. Taking the absolute size of the Vorticity vector and plotting its distribution at each time step is about the best one can hope for in easily emulating what a Rheoscopic fluid shows.

The beauty of CFD is that it ‘instruments’ a flow field at 1000s of points, unobtrusively. From that, various post-processing techniques can be used to create views and animations of the fluid dynamics. This enables much greater insight into the reasons for the observed flow than could ever be obtained experimentally, be it using Rheoscopic fluids, hot wire anemometry, particle image velocimetry, laser Doppler velocimetry, interferometry, tracers etc. Tavakol, M.M.; Abouali, O.; Yaghoubi, M. Large eddy simulation of turbulent flow around a wall mounted hemisphere. Appl. Math Model 2015, 39, 3596–3618. [ Google Scholar] [ CrossRef] When using CFD to simulate turbulent flows it is common to adopt a ‘Reynolds Averaged Navier-Stokes’ (RANS) approach. With RANS all the turbulent vortices are considered time-averaged by the equations that are solved. Think of it as the simulation equivalent of taking a long exposure time photo. Alternatively the turbulence can be simulated more explicitly by taking a Direct Numerical Simulation (DNS) approach. Here the computational mesh cells and time steps used are small enough to resolve all the eddies, down to the smallest scales. More like a high resolution camera with a very short time exposure taking multiple pictures over time.

The card system is dodgy. We weren't fully informed on how it worked and on many occasions double tapped the card readers thinking we had to collect our points after playing by tapping.....but it automatically added points to the game, so what was happening was that we were tapping to play again.

I thought to myself “What a great tool the Dome’s immersion experience is to blow out our old and outdated mindset, be it our mindset around our self-leadership, or the leadership of our team(s) or organization!” Witnessing the effects of the 360 °immersive environment and interactive technologies — as companies such as Nike, Nokia, and Xbox have done to create brand activation — can definitely be a portal for leadership transformation.
