Explore a groundbreaking mathematical framework for modeling turbulent fluid motion in this comprehensive lecture. Delve into a novel approach that departs from the traditional Reynolds decomposition, yielding closed and solvable ordinary differential equations in matrix form. Discover how the linear terms in the Navier-Stokes equations correspond to a symmetric matrix operator, while the nonlinear convective term acts as an anti-symmetric operator coupling eigenstates of turbulent fluctuation. Examine the derivation of the turbulent energy spectrum, including the Kolmogorov energy cascade, and gain insights into instability mechanisms for the transition to turbulence. Learn about the analytical solution for turbulence in a box, with emphasis on both the physical picture and rigorous mathematical foundations. Conclude by exploring current efforts to implement this model into numerical simulations at ReynKo Inc., offering a glimpse into the future of turbulent fluid dynamics research.
