Experimental investigation of the Near Wake of a Trailer model

In this paper we present results of an experimental program that aims at gaining a better understanding of the flow in the near wake of a trailer. We consider the effects of different velocity at the input on the trailer wake parameters. Turbulence intensity and average velocity Charts is plotted for four different velocities. Turbulence intensity and average velocity has been investigated by taking distance from the end of model. Analysis of the flow in the near wake of Trailer shows two maximum values for turbulent intensity because of the interaction between the shear layers of upper and lower surfaces of model and the wake region.
