The influence of free-stream dissipational scale and turbulence level in the boundary layer on a smooth flat-plate with zero pressure gradient have been investigated. By using of known experimental and numerical data comparison the problem of transition modeling from laminar boundary layer to turbulent by numerical methods under various k-ε turbulence models with two additional transport equations have been studied. The effect of initial turbulence profile distributions have been observed on forming transition region and its location.
