摘要
The kinematic and the diffusive properties of an up-wind directed jet have been identified by a thermal marking technique. Sixty-six fast response thermocouples, placed in the plane of the jet exit, were used to record instantaneous planes of T(x=0, y, z) for two velocity ratios: Vj/U=2.3 and 1.3. In agreement with the observations from T.U. Berlin, these ratios represent relatively unstable (2.3) and relatively stable (1.3) kinematic fields.
