Overview

Randomized trial analyzes pollutant diffusion in high-rise buildings, suggesting improvements for public health.

Key Points

  • This study aims to analyze how thermal and wind conditions affect pollutant dispersion in high-rise buildings.
  • Conducted transient CFD simulations using field-measured wall temperatures and window wind velocities.
  • Investigated vertical diffusion of buoyant (CH4) and dense (CO2) pollutants in a high-rise residential building.
  • Analyzed the effects of thermal pressure, window velocity, and wind-thermal coupling.
  • Under wind-thermal coupling, pollutant diffusion rate is 200% faster than under thermal pressure alone.
  • CH4 shows 2–4 orders of magnitude higher concentrations and broader influence range compared to CO2.
  • Asymmetric diffusion patterns observed, with wind dominating the upper region and thermal effects in the lower.
