The present research is undertaken to further the physical understanding of the behavior of an embedded vortex in a three-dimensional turbulent boundary layer. The vectors of instantaneous transport of turbulent kinetic energy are large above the vortex and in the downwash region, in Case 2. The production terms are mainly contributed to the values of V^2 and W^2. Then these profiles show an elliptic shape centered on the peak vorticity point. Both the production and advection terms of turbulent kinetic energy fall rapidly between the first and second measurement stations. In Case 2, a region of high production develops in the upwash region. The contribution of production and advection results in a uniform high value of turbulent kinetic energy in the entire region above the vortex.
