Key structure in laminar-turbulent transition of boundary layer with streaky structures
Theoretical and Applied Mechanics Letters, 2019 A numerical simulation is performed to find out a key vortical structure in the laminar-turbulent transition. A low-speed streak is generated inside a laminar boundary layer using an isolated cuboid roughness, aimed at providing an environment unstable ...

Definition of Turbulent Boundary-Layer with Entropy Concept
MATEC Web of Conferences, 2016 The relationship between the entropy increment and the viscosity dissipation in turbulent boundary-layer is systematically investigated. Through theoretical analysis and direct numerical simulation (DNS), an entropy function fs is proposed to distinguish

On injection-ejection fluid influence through different accelerating porous surfaces on unsteady 2d incompressible boundary layer characteristics [PDF]
Theoretical and Applied Mechanics, 2005 Through the porous contour in perpendicular direction, the fluid of the same properties as incompressible fluid in basic flow, has been injected or ejected with velocity who is a function of the contour longitudinal coordinate and time. The corresponding
