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., 資料番号: NALTR0921000, レポート番号: NAL TR-921}, title = {Estimation of Up-Wash Distribution Around an Automobile by Three-Dimensional Smoke Wind Tunnel Test}, year = {1986} }
