TL;DR: In this paper, a new dimensionless number has been submitted, which is a ratio of the inertial force due to the oncoming flow acceleration in its global unsteady motion to the centrifugal inertial forces due to curved streamlines around the cylinder.

TL;DR: In this article, smoke image velocimetry (SIV) measurements of instantaneous two-dimensional velocity vector fields in complex turbulent flows with high spatial resolution of the order of Kolmogorov scale were obtained.

TL;DR: In this paper, experimental studies of heat transfer and kinematic structure of steady and pulsating air flows past a spanwise rib have been performed, and the authors have shown that the heat transfer coefficient over the wall in the rib wake correlates best with the distributions of transverse velocity component.

TL;DR: In this paper, a visual investigation of the flow structure in the near wake behind a transverse cylinder in a fluctuating flow is carried out, on a special setup, on wide ranges of the frequencies and amplitudes of superimposed fluctuations.

TL;DR: In this article, the relative head of a liquid-jet compressor grows with the apparatus inlet air pressure in the middle part of the curve, and a new original technique has been submitted and verified which is based on an inverse unsteady problem of gas pumping and allows derivation of the whole curve instead of one operating point.
