The flow conditions near the inlet of a radial Hele-Shaw cell significantly affect the outcome of its technological applications. The present work combines Computational Fluid Dynamics (CFD) and micro-Particle Image Velocimetry (μPIV) to explain the entrance phenomena, i.e. flow detachment and vortex generation, in radial Hele-Shaw cells. The experiments show that the flow detachment is determined by the inlet flow Reynolds number, Re. Two-dimensional numerical simulations were employed to further investigate the role of the gap width, w to inlet diameter, D aspect ratio, w/D. The resulting flow regime map is divided by a transitional Re number, Ret, that depends on the aspect ratio. A further parametric study examining how Re and the aspect ratio affect the reattachment length yields an empirical correlation in power-law form. Finally, the impact of the inlet's geometrical features is briefly examined. The current work can be used as a design guide for future radial HS engineering applications.</p>", "creator": [ { "@id": "https://orcid.org/0000-0002-1729-4426", "affiliation": "HZDR, TUD", "@type": "Person", "name": "Stergiou, Y." }, { "@id": "https://orcid.org/0000-0002-9671-8628", "affiliation": "HZDR, TUD", "@type": "Person", "name": "Eckert, K." }, { "@id": "https://orcid.org/0000-0002-4866-483X", "affiliation": "HZDR, TUD", "@type": "Person", "name": "Schwarzenberger, K." } ], "@id": "https://doi.org/10.14278/rodare.902", "@type": "Dataset", "sameAs": [ "https://www.hzdr.de/publications/Publ-32487" ], "@context": "https://schema.org/", "url": "https://rodare.hzdr.de/record/902" }
