In the urban housing aerodynamics project, investigates the effect of building spacing on cross-ventilation performance in an urban housing layout using Computational Fluid Dynamics (CFD). Numerical simulations were carried out in ANSYS Fluent based on a reference study comparing steady RANS, LES, and wind tunnel experiments. Three geometric cases were modeled, varying the distance between adjacent buildings (100 mm, 200 mm, and 300 mm), and meshed with high-quality tetrahedral elements. A k-ε turbulence model with a velocity inlet profile was applied to replicate realistic wind conditions. The results show that increasing the distance between buildings enhances airflow into the central house due to greater pressure differentials, leading to improved ventilation efficiency.

Tower aerodynamic project presents a CFD analysis of the Burj Khalifa (828 m) and Jeddah Tower (1000 m) under a steady 10 m/s wind using ANSYS Fluent. Geometries were built in SpaceClaim/Design Modeler and meshed in ANSYS Meshing, later converted into polyhedral elements for efficiency. A pressure-based steady solver with the Realizable k-ε turbulence model was applied, with velocity-inlet and pressure-outlet boundary conditions. Results show pressure drag dominates in both towers, while torque due to height is a critical factor, influenced strongly by tower geometry.

Comprehensive analysis of different CFD algorithms using a variable-width channel case study (5cm inlet, 10cm outlet, 20cm length). Pressure-based solvers (SIMPLE, SIMPLEC, PISO, Coupled) compared with density-based solvers (Roe, AUSM) for various flow conditions. SIMPLE algorithm excels in low-speed flows, while Coupled solver shows superior performance across all speed regimes. Density-based solvers (Roe, AUSM) perform best in high-speed and supersonic flows but struggle with low Mach numbers. Under-relaxation factors significantly impact convergence stability and simulation accuracy. Optimal solver selection depends on flow regime: low subsonic (SIMPLE/SIMPLEC), transonic/supersonic (Coupled/AUSM), hypersonic (Roe/AUSM).
