Recent theoretical and numerical investigations revealed the prospect that the instantaneous total temperature is nonuniform around vortices. For low Mach number flows, the instantaneous total pressure was also shown to become nonuniform in such a similar manner that the near-wake patterns of instantaneous total pressure exhibit almost exact facsimiles of these of total temperature. Here, the time-accurate measurements of the fluctuating total temperature and pressure are presented by placing an aspirating probe in the vortex street behind a cylinder. The data, obtained at a uniform upstream Mach number of 0.4 and with the vortex street in its natural (unexcited) state, show a significant fluctuation of total temperature and pressure. In addition, their time-traces taken in the near-wake are qualitatively similar. / M.S.
