Influence of Particle Shape on Tortuosity of Non-Spherical Particle Packed Beds

Tortuosity in packed beds or porous media is of significant interest many fields, from geoscience to the chemical industry. plays a role mass transport media, but also their residual thermal electric conductivity when particles are not conducting. Several predictive models have been proposed evaluate tortuosity, there still gap it comes considering various particle shapes. The preponderance tortuosity substantiated literature porosity-dependent while only few include shape parameters. In this work, we propose new model with sphericity and porosity predict based on simulations carried out non-conducting for domains no wall effect. generated rigid body compared studied different shapes range 0.65–1. Sphericity showed effect other 3D parameters (numbers faces, edges, vertices); therefore, has considered model. well suited 0.3 0.4. said ranges, an upgrade classical Zehner–Bauer–Schlünder (ZBS) effective beds, superior performance.
