Overview

Numerical study revealed turbulence impacts aerodynamic forces in a rectangular cylinder, indicating new simulation methods improve analysis.

Key Points

  • Increasing turbulence intensity significantly suppresses vortex shedding from the rectangular cylinder, improving aerodynamic performance.
  • The study shows large eddy simulation techniques can efficiently control inlet velocity distributions for wind-resistant analysis.
  • Key findings reveal that boundary conditions and wind speed have negligible effects on turbulence characteristics in flow fields.
  • This research provides valuable insights into aerodynamic forces in complex wind fields, supporting engineering applications for bluff bodies.
