An attempt to measure fluctuating local pressure in free turbulent flow in water

We developed a technique for the measurement of fluctuating hydraulic-pressure at an arbitrary point in turbulent flow. A pressure-measuring system was composed of a miniature static-pressure probe (SP-probe), a strain-gage-type pressure transducer, and a tube connecting them. A model equation of dy...

description We developed a technique for the measurement of fluctuating hydraulic-pressure at an arbitrary point in turbulent flow. A pressure-measuring system was composed of a miniature static-pressure probe (SP-probe), a strain-gage-type pressure transducer, and a tube connecting them. A model equation of dynamic response of the pressure-measuring system was introduced, and a calibration technique for determining parameters in the model equation was developed. Effects of the size of the SP-probe, length of the tube, and sensitivity of the pressure sensor were systematically investigated using several SP-probes, tubes, and pressure transducers with different sizes, lengths, and sensitivities, and fluctuating hydraulic-pressure measurement was performed in a wake of a circular cylinder.
