Where complex fluids meet computation
Since 1979, the International Workshop on Numerical Methods for Non-Newtonian Flows has convened the researchers who build the equations, algorithms and codes behind our understanding of fluids that refuse to behave like water. Born from a small circle of pioneers troubleshooting the notorious “High Weissenberg Number Problem,” the series has grown into the field’s longest-running gathering, moving biennially between Europe, Israel and, more recently, the Americas. It remains a small, residential meeting by design — days spent in the same rooms and the same coastline produce the kind of conversation a conference hall rarely does.
N² Flows 2027 carries that tradition into a new era for the field: as machine learning, physics-informed neural networks and data-driven constitutive modelling reshape how we simulate complex fluids, the workshop's founding question — how do we compute what non-Newtonian materials actually do? — is being asked again with new tools. In Chania, on the north-west coast of Crete, we will bring together applied mathematicians, computational scientists and engineers working on viscoelastic, viscoplastic, granular and multiphase flows — from polymer processing and enhanced oil recovery to blood, mucus and the AI methods now entering all of them.
The setting carries its own history. Chania, a Venetian and Ottoman port city, is also the birthplace of Eleftherios Venizelos, and the workshop will be hosted at his family home — now the National Foundation for Research and Studies “Eleftherios K. Venizelos” — a research institution that has kept the city's connection to scholarship and public life alive for decades. N² Flows 2027 is held under the auspices of the Hellenic Society of Rheology, and organised by TheFluidsLab, Department of Chemical Engineering, University of Patras.
The Venizelos House, Halepa
N² Flows 2027 will be hosted at the National Foundation for Research and Studies “Eleftherios K. Venizelos”, headquartered in the statesman’s own family home in Halepa — Chania’s 19th-century diplomatic quarter, where the great powers once kept their consulates along the seafront.
Built in 1877, the house sheltered Eleftherios Venizelos — modern Greece’s most consequential statesman — for more than thirty years. It is now preserved as a research foundation and house-museum, its rooms kept much as he left them.

- By airChania International Airport (CHQ), with connections via Athens (Athens International Airport, ATH) and direct flights from several European cities in May. Aegean Airlines operates indicatively 3–4 daily flights between Athens and Chania, a flight of about 45 minutes.
- By seaOvernight ferries connect Piraeus (Athens) to Souda, Chania’s port, in about 9 hours — an option worth considering with cabin berths for an overnight crossing. Operators include ANEK Lines and Minoan Lines.
- HalepaA short walk along the seafront from the old Venetian harbour, once lined with foreign consulates and still home to Chania’s grandest 19th-century mansions.
- FormatScientific sessions at the Foundation, with accommodation nearby — in keeping with the series’ long-standing residential format.
Forty-eight years of fluids that break the rules
Water thins under a spinning spoon exactly as Newton’s law predicts. Polymer melts, blood, drilling muds and wet cement do not — and forty-eight years ago, the equations built to simulate them kept failing at the moment they were needed most.

Marcel J. Crochet
Bruce Caswell
Ordinary conferences gave researchers nowhere to show a simulation that had actually broken. So in 1979, three founders — Bruce Caswell, Marcel J. Crochet and Kenneth Walters — set up an invitation-only, residential workshop where failure could be put on the table and taken apart in the open.

Edition XVII, Blois, France (2012/13)
Following nearly every edition since the late 1980s, the workshop’s scientific outcomes have been documented in a peer-reviewed special issue of the Journal of Non-Newtonian Fluid Mechanics (Elsevier) — a record that N² Flows 2027 intends to continue.

Where to stay
Halepa puts you within walking distance of the venue; Chania’s old town offers a wider range within a short bus, taxi or walk away. Suggestions below, not affiliated bookings.
Halepa — walking distance to the venue
The Venizelos House sits in Halepa itself; these stays are a 5–15 minute walk away.
Chania old town
More choice around the Venetian harbour, roughly 2–3 km from the venue.
Getting from Chania old town to the venue
Indicative options and costs for the ~2–3 km trip to Halepa.
Places around to see and visit
A few short walks from Halepa and the old town worth the detour.
Useful contacts
