要約

An attempt is made for simultaneous measurements of velocity and pressure in three-dimensional turbulent flows by means of a miniature pressure probe combined with a triple hot-film anemometer. A turbulent wing-tip vortex is chosen for the test case because of the strong fluctuation of velocity and pressure near its core region. Measurements are undertaken in the near field. The static pressure fluctuation and the velocity-pressure correlation are experimentally investigated. Although they showed distribution that is consistent with those in previous reports, the influence of probe interference needs be substantially reduced.
