This study explores a new approach to computational fluid dynamics (CFD) by directly utilizing 3D image data. We focus on processing point cloud data obtained via smartphone photogrammetry applications to simulate fluid flows around complex geometries. The core methodology involves the Immersed Boundary Method (IBM) combined with a level-set approach to define solid boundaries continuously within the computational domain. Our findings demonstrate the efficacy of this technique using a copper statue model, reconstructed from image data, to conduct flow simulations. Additionally, we present a case study of indoor airflow analysis, showcasing a robust simulation is possible even when the surface model is not closed. The results underline the feasibility of leveraging consumer-grade devices for accurate CFD analysis, offering an accessible and cost- effective solution for diverse fields.
