    "abstract": "In this paper, computations of transient, incompressible, turbulent, plane\njets using the discrete lattice BGK Boltzmann equation are reported. A priori\nderivation of the discrete lattice BGK Boltzmann equation with a spatially and\ntemporally dependent relaxation time parameter, which is used to represent the\naveraged flow field, from its corresponding continuous form is given. The\naveraged behavior of the turbulence field is represented by the standard {\\it\nk-$\\epsilon$} turbulence model and computed using a finite-volume scheme on\nnon-uniform grids. Computed results are compared with analytical solutions,\nexperimental data and results of other computational methods. Satisfactory\nagreement is shown.",
