Wind Catcher Shaft Designs (with 10 floors)

This open-access repository contains the 3D CAD geometry files and simulation-ready models for four distinct passive windcatcher (Barjeel) shaft configurations (Models 0.0, 1.0, 2.0, and 3.0), designed for integration into 10-storey residential structures in arid coastal microclimates. Developed for comparative fluid dynamic analysis, these models evaluate the impact of internal vertical shaft partitioning on top-down natural ventilation performance in Computational Fluid Dynamics (CFD). The dataset includes dual-partitioned, quad-partitioned, and unpartitioned central shaft geometries created to study internal short-circuiting phenomena, static pressure drop distributions, and multi-storey volumetric flow rates. These files are published to support researchers, building physicists, and architectural engineers in optimizing climate-responsive passive ventilation systems for contemporary urban high-rises.
