摘要
This paper is concerned with the validation of a four-hole pressure probe, known as a cobra probe, for turbulence measurement. For the first time in the literature, third- and fourth-order velocity correlations measured using a pressure probe are presented. The probe measurements are compared with established data for fully developed pipe flow, and good agreement is round. A new probe calibration methodology and improvements to the data acquisition and processing system are also presented. (C) 2000 Elsevier Science Inc. All rights reserved.
