A new Euler-Lagrangian cavitation model for tip-vortex cavitation with the effect of non-condensable gas

Numerical simulation of tip vortex cavitation (TVC) remains a challenging task in a variety of applica-tions, such as axial turbines and pumps as well as marine propellers. Although it is well known that TVC is highly sensitive to gas content, be it dissol ...

Adhesive pads are commonly used in both natural and engineering systems. A recent study [Cohen et al. Soft Matter 2018] has shown that the failure of finite pads, subjected to loading parallel to the substrate, can be triggered by different mechanisms; int ...

The present study concerns the numerical homogenization of second order hyperbolic equations in non-divergence form, where the model problem includes a rapidly oscillating coefficient function. These small scales influence the large scale behavior, hence t ...

Finite Particle Flow Simulation of Free Jet Deviation by Rotating Pelton Buckets

Christian Vessaz

The prediction of hydraulic machines performances is of high interest to manufacturers in today's highly competitive market for new development or refurbishment of hydraulic power plant. An accurate prediction of the machines performances by numerical simu ...

Numerical modelling of gravel unconstrained flow experiments with the DAN(3D) and RASH(3D) codes

Vincent Labiouse, Claire Sauthier

Landslide continuum dynamic models have improved considerably in the last years, but a consensus on the best method of calibrating the input resistance parameter values for predictive analyses has not yet emerged. In the present paper, numerical simulation ...

Formation of drying crack patterns in soils : a deterministic approach

Lyesse Laloui, Hervé Péron

Soils, as well as most of deformable multiphase porous materials, are likely to suffer from desiccation cracking, leading to the formation of regular crack patterns affecting their permeability. The ensuing cracks spacing has often been related to a concep ...
