A high order finite difference scheme is introduced to deal with thermo-hydraulic quench simulation in superconducting magnets, specifically in the case of cable-in-conduit conductors (CICC). Liquid helium flow in CICC is governed by the unsteady convectio ...
This paper describes a photon-counting study of the cavitation luminescence produced by flow over a hydrofoil. This has previously been identified in water saturated with xenon. The four objectives of this study are: to determine whether luminescence can be ...
A numerical model is presented for the simulation of complex fluid flows with free surfaces in three space dimensions. The model described in Maronnier et al. (J. Comput. Phys. 1999; 155(2):439) is extended to three dimensional situations. The mathematical ...
Numerical simulation of the unsteady turbulent flow in a three-dimensional draft tube geometry is performed. The investigation is carried out with a commercial finite volume solver implementing the Reynolds averaged Navier-Stokes equations. The modeling of ...

A series of careful laboratory soil column experiments was carried out for the purpose of providing data for testing recently presented theories of miscible density-dependent flow and transport. In particular, modifications to the standard theory involve e ...
[1] During the winters of 1998 and 1999, observations were made of the cascading of cold water from the nearshore, shallow "shelf'' zones and down the sloping sides of Lake Geneva. Cascading starts on the average 10 hours after the onset of surface cooling ...
We consider the incompressible, isothermal and inertialess flow of an Oldroyd-B viscoelastic fluid in the absence of body forces. We report numerical results on the simulation of unsteady flow of an Oldroyd-B fluid by spectral element methods. Several tech ...
Flow in a elbow draft tube is a turbulent complex unsteady flow caused by its rotating nature and the draft tube's geometry. The understanding of the main phenomena that could appear near the BEP and at off-design conditions is important to master the inst ...

Numerical simulation of the unsteady turbulent flow in a three-dimensional elbow diffuser is performed. The investigation is carried out with a commercial finite volume solver implementing the Reynolds averaged Navier-Stokes equations. Against the backgrou ...
We present some results on coupling Navier-Stokes with shallow water equations for surface flows, and with Darcy's equation for groundwater flows. We discuss suitable interface conditions and show the well-posedness of the coupled problem in the case of a ...
