DESIGN AND CALIBRATION OF A TOTAL-PRESSURE PROBE FOR DUST-LADEN AIR
Abstract
A total-pressure probe was designed and tested for use in high-velocity airstreams which are heavily laden with dust, specifically in airblasts from field tests of nuclear weapons at low heights of burst over a desert surface. Analysis predicts that the probe should measure nearly independently and with high-frequency response the total pressure of the gas phase and the momentum flux of suspended particulate, provided that the particles range in size from about 2 to 20 microns. Experimental results are in agreement with the prediction that the probe should respond to about one-half the momentum flux of particles in this size range. The response of the probe to dust decreases rather rapidly as the particle size departs from this range and al o as the angle of attack of the probe becomes large. (Author)
