In  thepresent work, we study numerically the localized turbulence in pipe flow and elucidate astate space structure that gives rise to transient chaos. Starting from the basin boundaryseparating  laminar  and  turbulent  flow,  we  identify  transverse  homoclinic  orbits,  thepresence of which necessitates a homoclinic tangle and chaos. A direct consequence ofthe homoclinic tangle is the fractal nature of the laminar-turbulent boundary, which wasconjectured in various earlier studies. By mapping the transverse intersections between thestable and unstable manifold of a periodic orbit, we identify the gateways that promote anescape from turbulence.","lang":"eng"}],"date_published":"2019-10-01T00:00:00Z","page":"102401","publication_status":"published","month":"10","date_updated":"2023-08-30T07:20:03Z","publisher":"American Physical Society","day":"01","oa_version":"Preprint","volume":4,"intvolume":"         4","scopus_import":"1","date_created":"2019-11-04T10:04:01Z","year":"2019","type":"journal_article","citation":{"ama":"Budanur NB, Dogra A, Hof B.
