MACH NUMBER 3 TO 8 CALIBRATIONS OF A 30-DEG CONICAL PROBE

Arliss Dean Ray

Abstract

Abstract : An experimental evaluation of the Mach number and flow angularity measuring capabilities of a 30-deg half-angle conical probe is presented. Probe calibrations were conducted over a Mach number range from 3 to 8 and a unit Reynolds number range from 0.6 x 10 to the 6th power to 14 x 10 to the 6th power per foot. The probe sensitivity to flow angularity was essentially unaffected by Mach number and Reynolds number under the conditions investigated. Mach number sensitivity was reduced with increased Mach number.
