| Abstract |
Flow element model is used for predicting indoor air distribution. The greatest assets of the flow element models are the fact that they are relatively easy to use, they require only a few input parameters, they are not very timeconsuming and they do not demand any investments of importance. Because the flow elements such as supply air jets, exhaust flows, thermal plumes, boundary layer flows, infiltration and gravity currents are controlled by the restricted number of parameters, the flow element model will be useful at the first stages of design process. Air distribution with inclined jets is widely used in large rooms of industrial and commercial buildings when chilled air is supplied through the grilles and nozzles.??In this paper, Basic principles of air distribution with inclined jets through grilles and nozzles are discussed. In this study, computer program is developed to evaluate the dimensions of the occupied zone effectively ventilated by the jets through studies of airflow parameters after impingement of inclined jets with surface. |
