摘要: The present study concerns analysis of advective-diffusive transport in prototypical industrial mixing devices by the diffusive mapping method. latter is a recent extension conventional method for distributive and enables application this efficient technique to flows, including molecular diffusion. Primary challenge detailed numerical flow properties inside realistic systems with complex geometries. This performed combining sophisticated computational scheme simulations domains (moving) boundaries: eXtended Finite Element Method (XFEM). are investigated through spectral way eigenmode decomposition matrix. Key topic correlation between evolution concentration fields invariant Lagrangian structures field.
