    Abstract: As the need for efficient heat extraction grows with decreasing extraction areas, enhancing heat transfer device performance is crucial. Porous structures in thermal devices like heat pipes and vapor chambers can significantly improve heat transfer. Permeability, vital in fluid dynamics, affects fluid flow in porous materials, such as lattice structures. This study uses numerical analysis to assess the permeability of lattice structures, created using nTopology and analyzed with ANSYS Fluent software. It focuses on Octet, Isotruss, and Diamond lattice geometries. The research considers lattice geometry, unit cell characteristics, flow conditions, and other factors to deeply understand these structures' behavior. Insights into how different parameters influence lattice behavior and permeability are gained. The study also examines the impact of beam thickness and porosity on lattice performance. By varying and comparing these aspects, the study seeks to develop a more thorough framework for permeability research, contributing to advancements in lattice structure design and engineering applications.
