This study presents a simplified model for shear flows developed to capture essential features of turbulence using a sparse representation based on intense structures called vortons. These dynamically regularized quasi-singularities interact with large-scale shear and give rise to two distinct flow regimes: a laminar regime governed by large-scale dissipation and a turbulent regime driven by vorton activity. Remarkably, the model reproduces power-law scaling behaviors consistent with classical turbulence, offering a compact yet insightful tool for investigating energy transfer and dissipation in complex flows.
