Selection of model for the numerical study of the convective jet problem

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