Abstract
This paper shows computer-aided air flow visualization(CAFV) of exhaust air from outdoor unit of air-conditioners which are installed on every floor of a multistory building. After generating the complicated orthogonal meshs with automated fluid/solid cell determination thermo-fluid flow analysis is carried out with the Finite Volume Method Solver specially turned for air-conditioner simulation. Then, the results obtained are visualized through a highly interactive 3-D graphic display. Three dimensional colored contours and color fringes of temperature distributions visualize the convection flow along the building surface which is induced by the hot exhaust air from the outdoor units. Three dimensional vector display also help us understand the complicated flow structure around the outdoor units.
