Design and construction
of a new water tunnel
To achieve the full capability of the time-resolved tomographic
Particle Image Velocimetry (PIV) system for turbulence and
unsteady aerodynamics research, a
variable pressure water tunnel is currently been constructed
and shakedown tested in the lab. The tunnel is planned to
be fully commissioned by Fall 2017.
Extension of
the 2D pressure reconstruction code to 3D
A new Rotating Parallel Ray Algorithm for pressure reconstruction
based on PIV measurement is introduced (AIAA
Paper 2016-1049). 3D code development based on the new
algorithm is underway.
Investigation
of the influence of sub-grid scale stress on the accuracy
of pressure measurement
Quantifying the influence of the sub-grid scale stress on
the accuracy of pressure measurement is of theoretical and
practical importance. In the project, we use box filtering
to filter three dimensional velocity components in both the
isotropic turbulence and the turbulent channel flow fields
available to public from the John Hopkins University Turbulence
Database (JHTDB). Then we reconstruct the pressure based on
the filtered velocity data and compare it to the filtered
DNS pressure, thus gauging the error due to the measurement
resolution effect (see details in our PIV
2015 Paper and AIAA
Paper 2016-3403).

force reduction.
