Background:　There　are　a　large　number　of　rotating　devices　and　components　in　industry　where　flow　around　bluff　body　is　very　common.&　nbsp;Method:　In　order　to　study　the　characteristics　of　the　flow　around　the　bluff　body　in　centrifugal　field,　a　rotating　disk　is　used　to　produce　a　thin　rotating　liquid　flow,　then　dyeing　solution　is　used　as　a　tracer　to　study　the　wake　of　the　flow　around　a　cylinder　in　the　rotating　liquid　flow　which　is　recorded　by　a　high-speed　camera,　and　the　corresponding　simulation　is　also　proposed　by　using　large　eddy　simulation　(LES)　model.&　nbsp;Significant　findings:　The　results　show　that　the　St　number　increases　with　the　increase　of　the　rotating　Reynolds　number　&　nbsp;(Re-r),　and　decreases　with　the　increase　of　the　imported　Reynolds　number　&　nbsp;(Re-j)　in　the　range　of　3123　＜=　Re-r　＜=　7026,　1406　＜=　Re-j　＜=　2461.　Comparisons　show　that　most　experimental　and　simulation　results　of　both　St　number　and　&　nbsp;theta(s)&　nbsp;differ　by　less　than　20%,　which　indicate　that　LES　model　could　well　describe　the　characteristics　of　the　wake　of　the　flow　around　circular　cylinder　in　the　centrifugal　field.　The　results　provide　basis　for　the　flow　around　bluff　bodies　in　industrial　rotating　equipment.&　nbsp;　(C)&　nbsp;2022　Taiwan　Institute　of　Chemical　Engineers.　Published　by　Elsevier　B.V.　All　rights　reserved.
