Stochastic Superparameterization in a One-dimensional Model for Wave Turbulence
Superparameterization is a multiscale numerical method wherein solutions of prognostic equations for small scale processes on local domains embedded within the computational grid of a large scale model are computed and used to force the large scales. It was developed initially in the atmospheric sciences, but stands on its own as a nascent numerical method for the simulation of multiscale pheno...
متن کاملA One-Dimensional Model for Dispersive Wave Turbulence
A family of one-dimensional nonlinear dispersive wave equations is introduced as a model for assessing the validity of weak turbulence theory for random waves in an unambiguous and transparent fashion. These models have an explicitly solvable weak turbulence theory which is developed here, with Kolmogorov-type wave number spectra exhibiting interesting dependence on parameters in the equations....

متن کاملTwo-dimensional elastic turbulence.
We report numerical evidence of elastic turbulence phenomenology in a two-dimensional periodic Kolmogorov flow. By direct numerical simulations of the Oldroyd-B viscoelastic model at very small Reynolds numbers, we find that above the elastic instability threshold the flow develops an elastic turbulent regime. We observe that both the turbulent drag and the Lyapunov exponent increase with the W...
متن کاملProtecting Surfaces Using One-Dimensional Nanostructures
Ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. Protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. The importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. Up t...
