TL;DR: In this paper, a direct numerical simulation of incompressible channel flow at a friction Reynolds number of 5186 has been performed, and the flow exhibits a number of the characteristics of high-Reynolds-number wall-bounded turbulent flows.

TL;DR: An axisymmetric computational model is presented to study the heating processes of gold nanoparticles, specifically nanorods, in aqueous medium by femtosecond laser pulses, using a two-temperature model for the particle, a heat diffusion equation for the surrounding water, and a thermal interface conductance to describe the coupling efficiency at the particle/water interface.

TL;DR: The output from a direct numerical simulation of turbulent channel flow at Reτ ≈ 1000 is used to construct a publicly and Web services accessible, spatio-temporal database for this flow, and the results are compared with those of the equilibrium wall model, showing the strengths of the integral wall model as compared to the equilibrium model.

TL;DR: In this article, the authors investigated the transport equations for velocity variances using data from DNS of incompressible channel flows at up to 5200, and showed that the energy is transferred from the streamwise elongated modes to modes with a range of orientations through nonlinear interactions.

TL;DR: In this article, the authors investigated the transport equations for the variances of the velocity components using data from direct numerical simulations of incompressible channel flows at friction Reynolds number up to.
