内容記述 | In an aerodynamic experiment with a hang glider wing mounted on a running automobile, it is necessasry to correct the effects of the up-wash flow field induced by the automobile itself since they significantly deteriorate the measurement accuracy. Streamlines around an automobile model were observed in a three-dimensional smoke wind tunnel. The up-wash distribution was estimated from the shape of the streamlines. The measured up-wash distribution was found to be well approximated by that of an equivalent Rankine Oval, so that the oval, as a whole, could replace the automobile’s wake shape. By selecting appropriate Rankine Ovals, up-wash distributions can easily be estimated at arbitrary positions around an automobile, except in the separated flow region. The amount of side wall correction is also described in this paper. | |||||
