Tailor-made solution for volumetric ﬂow measurements
In the last few years a new technique called Tomographic PIV (TOMO-PIV) has been developed. TOMO-PIV is a volumetric three-component velocimetry technique. Full velocity and velocity radient tensor ﬁelds can be obtained from the TOMO-PIV method, which can provide comprehensive information on complicated three-dimensional ﬂows like turbulent boundary, including the nature and distribution of coherent vortex structures.
“Tomography” is a word originally from medical science meaning imaging by sections or sectioning through the measurement volume.
