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, pha...

A mesh adaptation methodology for wall-modeled turbomachinery Large Eddy Simulation (LES) is proposed, simultaneously taking into account two quantities of interest: the average kinetic energy dissipation rate and normalized wall distance y+. This strategy first tested on a highly loaded transonic blade with separated flow, compared to wall-resolved LES results, as well experimental data. The a...

Measurement of cardiac output is often investigated using a technique based on hot-film anemometry. Here, we discuss a modification to hot-film anemometry, which involves a cylindrical heating element mounted flush on the surface of a typical Swan-Ganz catheter. In contrast to traditional thermodilution, the method discussed here has the potential to allow continuous monitoring of cardiac outpu...

In this paper, synthetic jet actuators (SJAs) with three different orifice shapes (circular, square, and slot) the same cross-section area were investigated. The SJA efficiency (SJ) Reynolds number calculated based on time-mean reaction force measurement. momentum velocity was measured hot-wire anemometry additionally, sound pressure level (SPL) measured. equal maximally to 5.3% for each shape,...

This thesis is motivated by the necessity to understand the flow structure of turbulent flows in bends encountered in many technical applications such as heat exchangers, nuclear reactors and internal combustion engines. Flows in bends are characterised by strong secondary motions in terms of counter-rotating vortices (Dean cells) set up by a centrifugal instability. Specifically the thesis dea...
