Abstract
Linear and nonlinear dynamics of localized disturbances in laminar incompressible two- and three-dimensional boundary layers was investigated using the temporal direct numerical simulation. Laminar base profiles were computed with a Runge-Kutta block-structured finite volume software package. The time evolution of localized disturbances have been computed using the periodical model in stream- and spanwise directions. Pseudospectral methods were applied for the space discretization of the incompressible Navier-Stokes equations. All stages of time-evolution of the disturbances from linear to nonlinear (saturated) stage were examined, turbulent velocity profiles and r.m.s. velocity fluctuations have been computed at saturated stages.
