Abstract In the present study, an existing test rig at Institute of Thermal Turbomachinery (ITS), Karlsruhe Technology (KIT), designed for generic film cooling studies is adopted to accommodate time-resolved stereoscopic particle image velocimetry (SPIV) measurements. Through a similarity analysis, geometry scaled by factor about 20. Operating conditions hot gas and air inlet exit can be impose...

Tunable Diode Laser Absorption Tomography (TDLAT) is a non-intrusive measurement technique for determining two-dimensional spatially resolved distributions of temperature and species concentration in high enthalpy flows. TDLAT combines infrared laser absorption spectroscopy with tomographic image reconstruction. The TDLAT technique has been implemented at the University of Virginia's Aerospace ...

Turbulence is known to enhance gas-liquid mass transfer and mixing of high Schmidt number dissolved gases in water by deforming the concentration boundary layer that develops at interface. Fundamental mechanisms surface renewal injection have been progressively evidenced throughout last decades, via fundamental experiments low mean shear turbulence interacting with flat interfaces water. Howeve...

In this study, a variation of the stacked stereoscopic PIV technique is proposed to perform fully volumetric (3-dimensions, 3-components) measurements average flow fields within single experiment through usage an automated traversing system that continuously scans SPIV light sheet over linear path. The simultaneous measurement traverse location and laser Q-switch pulse enables assignment instan...

The concept of “musical culture Cherkashchyna” is characterized as a complex system that includes musical values, types activities related to them, set subjects, institutions and social institutes this type activity. Cherkashchyna presented an integral part the spiritual Ukraine Ukraine.

Children born with univentricular heart disease typically must undergo three open heart surgeries within the first 2-3 years of life to eventually establish the Fontan circulation. In that case the single working ventricle pumps oxygenated blood to the body and blood returns to the lungs flowing passively through the Total Cavopulmonary Connection (TCPC) rather than being actively pumped by a s...

The lean blowout mechanisms of premixed bluff-body flames are experimentally investigated at various turbulence intensities. Turbulence levels varied using a novel generator, which combines static grid and fluidic jet impingement techniques. Three different probed to study their effects on blowout. three conditions span across the combustion regime diagram, from flamelets broken reactions. For ...

An experiment was performed using stereo particle image velocimetry (SPIV) in the Laboratoire de Mécanique des Fluides Lille boundary layer facility to determine all derivative moments needed estimate average dissipation rate of turbulence kinetic energy $\epsilon = 2 \nu \langle {\mathsf{s}}_{ij}{\mathsf{s}}_{ij} \rangle$ , where ${\mathsf{s}}_{ij}$ is fluctuating strain and $\langle ~\rangle$...
