    Passenger Terminal Building (PTB) is a very important feature of a modern, international airport complex. Expansion of airport is aimed at design and construction of additional buildings and facilities to service growing international and domestic passenger traffic. Baggage reclaim hall on the arrival side and check-in hall on the departure side are large volume spaces in PTB, requiring proper distribution of conditioned air for adequate human comfort. In this class, how Autodesk CFD is used to evaluate air-conditioning design is presented. Importance of airflow and temperature distribution from CFD results is highlighted to ascertain indoor air quality and thermal environment. Strategies for modeling airflow and heat transfer are detailed out with best practices for flow and heat load characterization. Challenges of unacceptable thermal environment (hot spots) are addressed through design changes and optimization of supply flow rates and discharge angles, resulting in better designs.
