Theoretical and Applied Mechanics Letters, 2022 The exact similarity solutions of two dimensional laminar boundary layer were obtained by Blasius in 1908, however, for two dimensional turbulent boundary layers, no Blasius type similarity solutions (special exact solutions) have ever been found.

Numerical study of the effect of sidewalls on shock train behaviour
Flow, 2023 Strongly coupled sequences of shock waves, known as shock trains, are present in high-speed propulsion systems, where the presence of sidewalls substantially modifies the boundary layer thickness, skin friction and streamwise pressure distribution.

Propulsion and Power Research, 2020 This experiment used a parallel array of hot wire probes to simultaneously measure the temperature and velocity fields in the non-isothermal turbulent boundary layer of a rotating straight channel. The Reynolds numbers are 15,000 and 25,000, respectively.

Modeling the wall shear stress in large-eddy simulation using graph neural networks
Data-Centric Engineering, 2023 As the Reynolds number increases, the large-eddy simulation (LES) of complex flows becomes increasingly intractable because near-wall turbulent structures become increasingly small.

Tracking of vortices in a turbulent boundary layer
Journal of Fluid Mechanics, 2011 AbstractThe motion of spanwise vortical elements and large-scale bulges has been tracked in the outer region between wall-normal distance $z/ \delta = 0. 11$ and 0.30 of a turbulent boundary layer at ${\mathit{Re}}_{\theta } = 2460$. The experimental dataset of time-resolved three-dimensional velocity fields used has been obtained by tomographic ...
