Data and code for the article "Same programme, different fold". CFD of natural ventilation among the units of double loaded apartment floors with four plan shapes

Code, case settings and results that support the article "Same programme, different fold. Plan shape, corridor openings and the distribution of natural ventilation among units in double loaded apartment buildings under a tropical monsoon wind rose" (submitted to the International Journal of Ventilation).

The study compares four plan shapes (I, L, Z and C) and two corridor variants of one hypothetical floor of 36 identical units in a double loaded apartment block. Steady RANS simulations (OpenFOAM 12, SST k–ω) solve the external flow, the corridor and all units together for eight wind directions, which are weighted with the hot season wind rose of Vinh, Vietnam. The building is a hypothetical design and does not reproduce a particular building.

The archive contains:

• code/ the geometry generator, the OpenFOAM case builder and run manager, the analysis scripts and the figure scripts (Python);
• config/ the JSON settings of the runs used in the article;
• data/ the air change rate and opening flow rates of every unit for every configuration, wind direction and floor, the door scenarios, three mesh sensitivity triplets, the validation against the wind tunnel data of Tominaga and Blocken (2015) and the wind rose weights;
• figures/ the figures of the article (PDF);
• README.md the file list, a glossary of the Vietnamese file and column names and the steps to reproduce the results.
