Query: The Effort of Increasing Reynolds Number in Projection-Based Reduced
  Order Methods: from Laminar to Turbulent Flows   We present two different reduced order strategies for incompressible
parameterized Navier-Stokes equations characterized by varying Reynolds
numbers. The first strategy deals with low Reynolds number (laminar flow) and
is based on a stabilized finite element method during the offline stage
followed by a Galerkin projection on reduced basis spaces generated by a greedy
algorithm. The second methodology is based on a full order finite volume
discretization. The latter methodology will be used for flows with moderate to
high Reynolds number characterized by turbulent patterns. For the treatment of
the mentioned turbulent flows at the reduced order level, a new POD-Galerkin
approach is proposed. The new approach takes into consideration the
contribution of the eddy viscosity also during the online stage and is based on
the use of interpolation. The two methodologies are tested on classic benchmark
test cases.
