Toward computing sensitivities of average quantities in turbulent flows
Nisha Chandramoorthy, Zhong-Nan Wang, Qiqi Wang +1
Chaotic dynamical systems such as turbulent flows are characterized by an exponential divergence of infinitesimal perturbations to initial conditions. Therefore, conventional adjoi…
