  In this work, we present a localized form of the dynamic eddy viscosity model
for computationally efficient and accurate simulation of the turbulent flows
governed by Euler equations. In our framework, we determine the dynamic model
coefficient locally using the information from neighboring grid points through
a test filtering process. We then develop an optimized Gaussian filtering
kernel, using a consistent definition with respect to the test filtering ratio,
which gives full attenuation at the grid cut-off wave number. A systematic
a-posteriori analysis of our model is performed by solving two 3D test
problems: (i) incompressible Taylor-Green vortex flow and (ii) compressible
shear layer turbulence induced by Kelvin-Helmholtz instability to show the wide
range of applicability of the proposed localized dynamic model. We demonstrate
that the proposed dynamic model is robust and provides a better estimation of
the inertial range turbulence dynamics than other numerical models tested in
this study.
