Abstract
En 中文
• Uniform and gradient Voronoi-based foams are constructed and numerically analyzed. • Deposition is governed by Brownian transport coupled with particle–wall interactions. • Higher PPI foams yield faster deposition rates and higher nanoparticle retention. • Inlet-side high-PPI gradients enhance early-stage nanoparticle capture efficiency. • NDL , rather than dp or NE1 , controls adhesion in the high-attraction regime.
