Conclusion

Use of supercomputer

As we have seen the turbulent flow which is described by the Navier-Stokes equations is characterized by a wide range of scales and because there is no analytical solution of the Navier-Stokes equations, The scientific community has focused on the numerical solution.

The Blue Gene/P supercomputer at Argonne National Lab runs over 250000 processors using normal data center air conditioning, grouped in 72 racks/cabinets connected by a high-speed optical network | Information^[1]

The numerical solution of the governing equation involves the resolution of the different scale of turbulence

→ Use of supercomputer : The computation cost is very high.
