Abstract

Total and static pressures are vital measurements in any supersonic experiment. By measuring these two pressures, the Mach number can be inferred. Most flows of interests are highly three dimensional, but with moderate swirl. Because of this three-dimensionality, the total and static pressures must be measured ideally at the same location. A miniature probe of 10deg. half-angle was designed and experimentally calibrated to asses the effectiveness of the Krasnov similarity laws to scale the influence of the truncated tip on the downstream cone surface pressure distribution. A recently developed uncertainty quantification approach based on polynomial chaos has been used to quantify the effect of geometric uncertainty coming from probe manufacturing tolerances on the measured Mach number utilizing computational fluid dynamics. The relative variation in the Mach number due to geometric uncertainty was found to be less than 1.0%. The cone angle 'was determined to be the most dominant uncertain geometric parameter on the results as a result of a sensitivity analysis. The applicability of the Krasnov similarity laws is proposed as a mean to circumvent or guide the traditional and expensive experimental approach used for the calibration of a multi-hole conical probe at zero angle of attack.
