The heat released by local exhaust ventilation is one of the most common hazards emitted during various industrial processes in industrial buildings. This work solves problems in order to find the numerical solution model that most adequately describes the development of a free convective jet above a flat heat source and a convective jet near the side hood located above the heat source. Various turbulence models and options of wall functions are considered for application in the study of a free convective jet. The data showed that the closest to theoretical results are those obtained when using the standard k-e model together with standard wall functions.
Key words: numerical method / turbulence models / wall functions / convective jet / local exhaust ventilation / side hood
