Experience of Direct Numerical Simulation of Turbulent Boundary Layers in Complex Flows

A survey is presented of numerical studies of near-wall turbulent flows conducted in different years using Direct Numerical Simulation (DNS) by representatives of three generations of L.G. Loitsyansky's students, currently working in the laboratory "Computational Hydroaeroacoustics and Turbulence" of SPbPU. Based on the experience accumulated in the course of these studies, a conclusion is drawn that despite the high computational costs required to carry out DNS, this method already today represents a powerful universal tool not only for fundamental research into turbulence, but also for solving important applied problems.
