Natural ventilation, a critical passive design strategy for indoor environmental regulation and urban pollution mitigation, relies heavily on dynamic wind patterns. However, existing studies predominantly focus steady or averaged directions, often overlooking transient effects caused by time-varying direction fluctuations. This study addresses this gap proposing novel meshing framework integrated into large eddy simulation in computational fluid dynamics simulations to investigate how time-dependent variations influence natural ventilation efficiency pollutant dispersion isolated buildings. The model divides the domain zone dynamically rotating zone, enabling realistic variability while preserving efficiency. Validation against tunnel experiments confirmed high accuracy. Results indicate that even minor directional fluctuations (1° amplitude) reduce rates 13.13% compared conditions, whereas larger amplitudes (40°) exacerbate retention, with relative concentration errors exceeding 150%. Frequency (5–40 s periods) exhibited negligible impacts amplitude-driven effects. Dynamic fields altered airflow suppressing shear layer separation forming low-pressure vortices, which disrupted diffusion pathways. A linear regression quantified amplitude-dependent decay, offering predictive capabilities scenarios. These findings highlight necessity of incorporating short-term models enhance building dispersion. proposed establishes scalable methodology design, providing physical insights optimize patterns under variability.
