Front propagation in a regular vortex lattice: Dependence on the vortex structure.
Phys Rev E
November 2017
Article Synopsis
- This study explores how vortex structures affect the movement of fronts in stirred flows, using both experimental and numerical methods.
- It finds that in extended vortex lattices with free boundary conditions, the shape of vortices doesn’t significantly influence front speed.
- However, in vortex chains with rigid boundaries, slight changes in vortex shape can noticeably slow down the front velocity, highlighting the complex relationship between vortex structures and flow dynamics in large-scale front propagation.
Article Synopsis
- The study explores how reaction-diffusion fronts move in vortex lattices using a controlled experimental setup in a Hele-Shaw cell.
- It differentiates between vortex chains (with mixed boundaries) and vortex arrays (with free boundaries) while observing their effects on front propagation.
- Results show that front velocities remain constant in vortex arrays but vary in vortex chains, challenging the understanding of front propagation behavior in low Reynolds number conditions.
