Abstract
The study of air flow and its modelling is particularly focused on designing double-cladding roofs, which are recommended for buildings in wet conditions. Software ANSYS [, which uses CFD method, is used for the modelling. The primary issue concerning the design of ventilated double-cladding roofs is to select the optimum thickness of air cavity. The study shows that the shape of streamlines in the ventilated cavity of a double-cladding flat saddleback roof is not based on the input velocity. Based on the selected model, there is a blind spot in between 1.76 m and 4.23 m of the outer edge of the attic where air back flow occurs at the bottom surface of the upper roof deck which leads to poor ventilation of the ventilated cavity.
