The FliHy (Flibe Hydrodynamics) facility was constructed at UCLA to study open channel turbulent flow and heat
transfer of low-thermal and -electrical conductivity fluids. At present, water is used as a stimulant fluid for molten salt,
e.g. Flibe. A similarity analysis matched the dimensionless parameters in the experiment with those in the ARIES-RS
First Wall design. Unlike previous studies of open channel flow, the goal of the present one is to study supercritical flow
regimes (Fr /1), in which the surface waves are amplified and heat transfer is enhanced due to surface renewal. The
paper describes the facility and gives the results of measurements of the flow thickness and their analysis.

1. Introduction
The Flibe Hydrodynamics (FliHy) facility was
recently established to study fundamental flow
physics, to assist in enabling liquid wall technology
and its application to reactor design. Early work
on FliHy mostly focused on shaking down the
facility, testing diagnostics, and obtaining proof of
