Mean and fluctuating pressure measurements over a circular cylinder in cross flow using plastic tubing

Not only can mean pressures on a surface over which a fluid flows be accura tely measured using a plastic tube which connects the surface tapping point s to a remote pressure transducer, but the fluctuating pressures can also, provided that the transfer function, which relates the fluctuating pressure s at the opposite ends of the tubing, is known. This technique was used her e to measure the mean and fluctuating pressures on the surface of a circula r cylinder subject to a cross-flowing airstream in the Reynolds number rang e from 6.8 x 10(4) to 9.6 x 10(4) based on cylinder diameter. Good agreemen t with published results gave confidence in the technique.
