The lift-up effect : The linear mechanism behind transition and turbulence in shear flows (2014, methodology): “In the same spirit, the importance of linear processes in wall-bounded turbulent shear flows has been investigated through numerical experiments in Kim and Lim (2000).”
Issues in active flow control: theory, control, simulation, and experiment (2004, background): “While there has been success in using linear control for wall bounded turbulence ranging from simple opposition control [83,87,107] to modern control theories [103,106], it seems likely that this success is due, in part, to the importance of linear processes in the near-wall region [94,95].”
A critical-layer framework for turbulent pipe flow (2010, background): “Several theories have been proposed to account for the missing physics in the classical scaling, including the mesolayer of Long & Chen (1981), the focus on the location of the Reynolds stress peak by Sreenivasan and co-workers (Sreenivasan & Sahay 1997) and the hierarchical structure associated wit”
Colour of turbulence (2016, background): “Kim & Lim (2000) highlighted the importance of linear mechanisms in maintaining near-wall streamwise vortices in wall-bounded shear flows.”
The engine behind (wall) turbulence: perspectives on scale interactions (2017, background): “The nonlinearity is important in setting the correct scales of the turbulence, but it is the linear dynamics, and specifically the coupling between wall-normal velocity and wall-normal vorticity, that control the generation and maintenance of turbulence (Kim & Lim 2000).”
Linear feedback control and estimation of transition in plane channel flow (2003, background): “Based on the findings reported by e.g. Henningson (1996); Farrell & Ioannou (1996) and Kim & Lim (2000), the importance of linear mechanisms for sustaining turbulence, especially the coupling between normal velocity and normal vorticity, indicate that linear controllers might also be useful in…”
The mechanism of streak formation in near-wall turbulence (2005, background): “Moreover, u can be represented as a sum of the averaged velocity U and a fluctuation, and numerical experiments show (Kim & Lim 2000) that it is the v∂U/∂y term that is responsible for the formation of streaks.”
Effect of Roughness on Wall-Bounded Turbulence (2004, background): “This numerical experiment was performed at Reτ = 180, since we wanted to compare the results with those in Kim and Lim [23].”
Componentwise energy amplification in channel flows (2005, methodology): “We remark that the numerical experiments of Kim & Lim (2000) indicated that without the coupling from v to ωy the near-wall turbulence decays in a fully turbulent channel flow.”
Flow control: new challenges for a new Renaissance (2001, background): “Indeed, recent numerical experiments by Kim & Lim (2000) support this idea by conclusively demonstrating the importance of the coupling term C in the linearized system matrix A (see equation (10)) for maintaining near-wall turbulence in nonlinear simulations.”
Overview of the self-sustaining mechanisms of wall turbulence (2001, background): “An interesting footnote to this section is the paper of Kim and Lim [102].”
