... engineering, the force fluctuation of cylinder is the main hazard for structures. In order to obtain precise time-varying forces asserted on the square cylinder, surface-flushed pressure sensors that could respond to high frequency force signals are required. The present surface-pressure measurement method...

... of turbulent flows through arrangements of singularities. The pressure measurements through the studied singularity, which is a simple and quite controllable method, enabled us to localize the recirculating zones in the diffuser. The obtained results on the static pressure helped us to correctly choose...
