Abstract:
The authors study radial solutions to a model equation for the Navier-Stokes equations.It is shown that the model equation has self-similar singular solution if 5 ≤ n ≤9.It is also shown that the solution will blow up if the initial data is radial,large enough and n ≥ 5.
Keywords:Navier-Stokes equations  Self-similar singular solutions  Blow-up
