An advanced prediction technique for use in wind tunnel pressure measurements

An algorithm is described which compensates for pneumatic lag effects in wind tunnel pressure measurement systems and thus significantly enhances data productivity. This algorithm is based on the Navier-Stokes equations for flow through a tube, with simplifying assumptions applied to predict orifice pressure from the time-varying transducer output. The validity of the algorithm for various pressure measurement systems is experimentally verified, and guidelines for the use of the technique are documented.
