🌀 Spiral Microchannel: Dean Vortices and Dye Mixing (2D top view)

2D top view of a spiral microfluidic channel in which two dye streams are stirred by Dean vortices. Change width, height, velocity, viscosity, diffusivity and number of turns, and watch the cross-section, the mixing index and the Reynolds and Dean numbers. Same particle model as the 3D page, with four in-page numerical checks.
