Abstract: In the present paper, numerical simulations of the flow around a special dynamic pressure sensor (Amplified Pitot tube), specifically designed and built as a Transfer Standard for a metrological Intercomparison, are presented and discussed. The computations allowed to obtain a good, and in some instances excellent, reproduction of the measurements. The CFD results were employed to analyze in detail the fluid dynamical phenomena around the sensor in order to clarify the reasons for some incoherences in the Intercomparison results. The indications of this preliminary work are that installation effects may play a role more important than previously expected for such cases.
