Characterization of coupling between inertial particles and turbulent wakes from porous disk generators

This study presents the findings of a wind tunnel experiment investigating behaviour micrometric inertial particles with Stokes numbers around unity in turbulent wake stationary porous disk. Various concentrations $\varPhi _{v}\in ([6-19] \times 10^{-6})$ poly-disperse water droplets (average diameter 40–50 $\mathrm {\mu }$ m) are compared sub-inertial tracer particles. Hot-wire anemometry, phase Doppler interferometry and particle image velocimetry were implemented near- far-wake regions to complex dynamics such Quadrant analysis is used explore shear effects interaction. Turbulence statistics size distributions reveal distinct differences structure when present flow. Additionally, there different structures near far change volume fraction.
