Aims to study the behaviour of airflow generated by multiple jets and introduced into a room. A finite volumes mathematical model was used in the study, in which the equations were linearised in implicit form and the domain was presented in its discrete elements using the finite volume method. The numerical simulation was performed by creating unstructured computational grids. Findings were compared to experimental data including an extensive series of measurement taken in a model environment setup in a laboratory. The air flow field of an occupied room was mapped in terms of mean air velocity and temperature making it possible to evaluate the comfort level perceived by occupants in the room. The study's purpose was to get reliable information relative to the velocity and temperature fields generated by batteries of jets with the aid of a scientifically sound model.
