Title: Numerical Analysis of Wind Load on Cross-Sections of Square, Pentagonal, Hexagonal and Staggered High Rise Buildings

Supervisor: Professor Dr. Mohammad Mamun, Department of Mechanical Engineering, Bangladesh University of Engineering and Technology

Description:

My senior year thesis project was based on such a predicament where people from third-world overpopulated countries with low income can overcome housing problems and reside in structures capable of withstanding large wind speeds. It was a computational fluid dynamics based project that focused on various flow parameters for turbulent flow across bluff bodies of different shapes and configurations at various angle of attacks. The whole study was aimed towards finding out the forces acting on buildings during high-speed flow and the potential critical areas of the buildings that may be susceptible to excessive load and failure.

Technical Details:

• A numerical investigation of wind load on square, pentagonal, hexagonal and staggered cylinders was carried out. The test was conducted around a cylinder in the flow direction of a uniform flow velocity of 14.3 ms-1 for cylinders of different shape
• Drag coefficient, lift coefficient and pressure coefficient were measured. Flow patterns for different geometry and angle of attack were also visualized
• The drag coefficient and lift coefficient were compared for a particular geometry for various angle of attacks
• The complete investigation was carried out on ANSYS Fluent platform based on Computational Fluid Dynamics
