Optimizing Wind Wing Wall Ventilation in High-Rise Buildings within Dense Urban Hot and Humid Climate.

This study investigates how wing walls can increase natural ventilation in high-rise structures, particularly in hot, humid locations such as Mumbai, India. Using wind flow simulations and computational fluid dynamics (CFD) modeling, the study investigates how wind direction and the installation of wing walls affect airflow throughout the building. The study examines four scenarios, each analyzing how airflow varies when a building is located near surrounding structures of differing heights. It uses comprehensive CFD simulations to assess how alternative wing wall depth design can affect ventilation, as well as how wall-to-window ratio variation can contribute to airflows. Following these simulations, the study compares airflow within the building to conventional ventilation benchmarks to identify which layouts provide the optimum comfort and air quality. It also compares the building's energy consumption without natural ventilation to the savings achieved by the most efficient wing wall designs. The purpose is to provide practical insights to architects, engineers, urban planners, and policymakers who design and build tall buildings in densely populated tropical cities. The study's goal is to promote greener urban development and more sustainable construction practices by demonstrating the potential of wing walls as a simple but effective architectural solution. Finally, this study seeks to inspire new ideas for improving energy efficiency, lowering costs, and fostering a more sustainable future in rapidly expanding cities.
