Analyzes vortex shedding & wind loads on Ping An Finance Center via ANSYS Fluent. 2D model, 417k-element mesh, k-omega SST, PISO solver. Flow at 15-25 m/s yields ~0.04 Hz vortex frequency, ~2.4 drag coefficient. Uses CFD. Aligns with aerodynamic research. This project investigates vortex shedding and wind load effects on the Ping An Finance Center using ANSYS Fluent. A 2D model with a 417,414-element mesh, k-omega SST turbulence model, and PISO solver was used to study flow at 15-25 m/s. Results show a ~0.04 Hz vortex frequency and ~2.4 drag coefficient, validated via FFT.

Analyze vortex shedding and wind loads on a high-rise building to ensure structural stability.

• Geometry: 2D model of Ping An Finance Center.
• Mesh: 417,414 elements, multizone quad/tri mesh.
• Solver: Transient simulation with k-omega SST model.
• Parameters:
  • Reynolds Number: 45,468,750 (turbulent flow).
  • Strouhal Number: 0.15.
  • Vortex Shedding Frequency: ~0.045 Hz.
• Software: ANSYS Fluent, (for FFT).

This was the first trial of my vortex shedding analysis. Since there was no symmetry in the setup, I re-centered the building in the domain and repeated the simulation.
