Present experimental research was intended to clarify the effect of the end plate in two dimensional turbulent plane jet in the hope that large discrepancies among previous reports about the evolution process could be explained, and to develop a turbulence detector for intermittency measurement.
Experimental results show that the end plate increases the decay rate of the center-line mean velocity, and the center-line turbulence intensity.
The turbulence detector based on the high kinetic energy dissipation rate, which is one of the major characteristics in turbulent flow, was found to work properly at the turbulent / non-turbulent interface. Intermittency measurements showed that the intermittency structure is self-preserving, and that it can be scaled by the mean flow variables in the far field of the plane jet where the mean flow shows similarity.
