摘要：

Instantaneous planar velocity and scalar distributions in a confined jet flow were measured simultaneously by PIV and PLIF methods. These distributions were used to calculate both cross correlation of velocity and scalar fluctuations and scalar gradients across and downstream the flow to validate the known approximations of turbulent scalar fluxes.
