Abstract
The development of a nearly-omni-directional pressure probe for three-velocity-component and pressure measurements is described, with particular focus on the techniques and technology employed in probe construction, calibration, electronic interfacing and frequency-response study. The device eliminates the velocity directionality limitations of current multi-hole probes and makes a valuable, rugged tool for use in complex 3-D flow mapping and aerodynamic design and evaluation, in basic research as well as industrial development settings. The probe performance is demonstrated in a flowfield with flow reversal downstream of a backward-facing step. The probe provides low-frequency response capabilities. The probe's main element is a multi-pressure port spherical head, which may include eighteen ports. Fiber optic interferometry techniques may be incorporated to significantly increase frequency response.
