Abstract

Ventilation is one of the important options in providing thermal comfort in buildings. Effective distribution of fresh air within an occupied space is of considerable importance in securing good indoor air quality, (IAQ). In natural ventilation systems, the fresh air is often provided through the opening of the window. The objective of this study is to predict the air flow characteristics via various window configurations and positioning. The air circulation inside an enclosure (room) with different opening was studied by mean of using the commercial Computational Fluid Dynamic (CFO) program CFX 5.7.1. The result of the standard K- ~ turbulence model is compared to previous journal that done by Per Heiselberg, Kjeld Svidt, Peter V.Nielsen, 2001. Characteristic of airflow from open windows. Alborg University, Denmark. This studied described the results of a simulation that performed on four different window types to determine the characteristic of the air flow in the room where the best window design is the sliding with bottom hung window at the top because it has big opening area and give more air circulation inside the room. The comparison between the computational and physical paper show good and acceptable agreement.
