Abstract
An automated meshing framework based on Voronoi tessellation is presented for the analysis of planar flow-control geometries relevant to fluid systems. The proposed approach eliminates manual boundary definition by directly converting rasterized representations of valve or channel layouts into un-structured computational meshes. The fluid domain is inferred from pixel-level information, enabling a fully automated image-to-mesh workflow adaptable to complex geometries. The methodology is applied to a representative diodic pipe configuration, a passive flow-control device capable of inducing direction-dependent pressure losses without moving components. Mesh generation is achieved through a raster Voronoi relaxation, resulting in geometry-adaptive discretization with enhanced resolution in constricted regions. The generated meshes are assessed through incompressible flow simulations, demonstrating good geometric conformity, numerical stability, and suitability for finite-volume discretization. The results indicate that the proposed meshing pipeline provides a robust and scalable tool for rapid preprocessing and analysis of passive flow-control systems in water treatment and hydraulic applications.
