Abstract

A flow control technique aimed to the drag reduction has been applied to a 3D simplified car model. In order to control the near wake region, four continuous jets are disposed at the periphery of the body. The control performance are previously analyzed through a preliminary CFD study on a 1:1 scale model. The preliminary experimental investigation in condition of wind off has been also considered on a 3D printed model at a 1:8.75 scale in order to assess the whole chain of measurements. This investigation involves the direct measurement of drag force, the pressure distribution on the surface of the model and the wall pressure fluctuations. Different requirements led to a particular mounting configuration for the model. Primary calibration of the load cell and the pressure fluctuations sensors has been carried out
