A streamwise constant projection of the Navier Stokes equations forced by small-amplitude Gaussian noise is simulated. It is found that this model captures salient features of fully developed turbulent plane Couette flow. In particular, the nonlinearity in the model captures the mathematical mechanism that results in the characteristic shape of the turbulent velocity profile. Further, using Taylor’s hypothesis the model also generates large scale streaky structures, that closely resemble large… CONTINUE READING
