摘要：
A model of turbulence with second-order closure is used to study the properties of turbulent jets with major variations in density. Validation of the performances of this model, which employs a Favre average procedure, is firstly presented by comparisons with experimental data from scientific literature and those obtained in the specific installation studied al IMST. Special attention is paid to the study of the interface region between the flow and the ambient environment, which demonstrates the present capacities and limitations of this type of model, particularly those associated with the properties related to anisotropy of Reynolds stresses.
