Direct Numerical Simulation (DNS)

Direct Numerical Simulation (DNS) is a computational method used to accurately model fluid flows by solving the fundamental fluid dynamics equations—Navier-Stokes equations—without approximations. It captures all scales of turbulent motion directly, providing detailed insights into complex flow behaviors. Because of its high resolution, DNS requires significant computational power and is typically employed for research purposes rather than everyday applications. It helps scientists understand turbulence and other fluid phenomena at a very detailed level, contributing to advancements in engineering, meteorology, and physics.
