Numerical simulations of the Navier - Stokes problem with hyper dissipation
نویسنده
چکیده
This paper proposes a numerical simulation of the incompressible viscous flows with hyper dissipation using Femlab. We propose two variational formulations to solve this problem: the primal and the mixed formulations. For the first one, a biharmonic formulation for the velocity and the pressure is used. The second one uses a mixed formulation where the laplacian of the velocity, the velocity and the pressure are the most relevant unknowns.

A comparative study between two numerical solutions of the Navier-Stokes equations
The present study aimed to investigate two numerical solutions of the Navier-Stokes equations. For this purpose, the mentioned flow equations were written in two different formulations, namely (i) velocity-pressure and (ii) vorticity-stream function formulations. Solution algorithms and boundary conditions were presented for both formulations and the efficiency of each formulation was investiga...
متن کاملOptimization with the time-dependent Navier-Stokes equations as constraints
In this paper, optimal distributed control of the time-dependent Navier-Stokes equations is considered. The control problem involves the minimization of a measure of the distance between the velocity field and a given target velocity field. A mixed numerical method involving a quasi-Newton algorithm, a novel calculation of the gradients and an inhomogeneous Navier-Stokes solver, to find the opt...
متن کاملA Cheap Caffarelli-kohn-nirenberg Inequality for Navier-stokes Equations with Hyper-dissipation
We prove that for the Navier Stokes equation with dissipation (−∆)α, where 1 < α < 5 4 , and smooth initial data, the Hausdorff dimension of the singular set at time of first blow up is at most 5− 4α. This unifies two directions from which one might approach the Clay prize problem.
متن کاملEnergy dissipation in body - forced plane shear flow
We study the problem of body-force driven shear flows in a plane channel of width ℓ with free-slip boundaries. A mini-max variational problem for upper bounds on the bulk time averaged energy dissipation rate ǫ is derived from the incompressible Navier-Stokes equations with no secondary assumptions. This produces rigorous limits on the power consumption that are valid for laminar or turbulent s...
متن کاملFinite Time Blow-up for a Dyadic Model of the Euler Equations
We introduce a dyadic model for the Euler equations and the Navier-Stokes equations with hyper-dissipation in three dimensions. For the dyadic Euler equations we prove finite time blow-up. In the context of the dyadic Navier-Stokes equations with hyper-dissipation we prove finite time blow-up in the case when the dissipation degree is sufficiently small.
