Numerical approximation of a PDE-constrained Optimization problem that appears in Data-Driven Computational Mechanics
Pedro B. Bazon, Cristian G. Gebhardt, Gustavo C. Buscaglia +1
We investigate an optimization problem that arises when working within the paradigm of Data-Driven Computational Mechanics. In the context of the diffusion-reaction problem, such a…
Chemoreception and chemotaxis of a three-sphere swimmer
Stevens Paz, Roberto F. Ausas, Juan P. Carbajal +1
The coupled problem of hydrodynamics and solute transport for the Najafi-Golestanian three-sphere swimmer is studied, with the Reynolds number set to zero and Péclet numbers (Pe) r…
A finite element method for simulating soft active non-shearable rods immersed in generalized Newtonian fluids
Roberto F. Ausas, Cristian G. Gebhardt, Gustavo C. Buscaglia
We propose a finite element method for simulating one-dimensional solid models moving and experiencing large deformations while immersed in generalized Newtonian fluids. The method…
A multiscale Robin-coupled implicit method for two-phase flows in high-contrast formations
Franciane F. Rocha, Fabricio S. Sousa, Roberto F. Ausas +2
In the presence of strong heterogeneities, it is well known that the use of explicit schemes for the transport of species in a porous medium suffers from severe restrictions on the…
Towards HPC simulations of Billion-cell Reservoirs by Multiscale Mixed Methods
A. Jaramillo, Rafael T. Guiraldello, Stevens Paz +4
A three dimensional parallel implementation of Multiscale Mixed Methods based on non-overlapping domain decomposition techniques is proposed for multi-core computers and its comput…
Interface spaces based on physics for multiscale mixed methods applied to flows in fractured-like porous media
Franciane F. Rocha, Fabricio S. Sousa, Roberto F. Ausas +2
It is well known that domain-decomposition-based multiscale mixed methods rely on interface spaces, defined on the skeleton of the decomposition, to connect the solution among the…
An extended Elrod-Adams model to account for backpressure and blow-by inception
Alfredo Jaramillo, Gustavo C Buscaglia
The Piston-Ring-Liner system is the main tribological component of internal combustion engines. The Elrod-Adams model is customarily used to numerically assess the hydrodynamics of…
Lagrangian statistics of pressure fluctuation events in homogeneous isotropic turbulence
Mehedi Bappy, Pablo M. Carrica, Gustavo C. Buscaglia
Homogeneous and isotropic turbulent fields obtained from two DNS databases (with $\mbox{Re}_λ$ equal to 150 and 418) were seeded with point particles that moved with the local flui…
Simulating squirmers with volumetric solvers
Stevens Paz Sánchez, Gustavo C. Buscaglia
Squirmers are models of a class of microswimmers, such as ciliated organisms and phoretic particles, that self-propel in fluids without significant deformation of their body shape.…
A stable numerical strategy for Reynolds-Rayleigh-Plesset coupling
Alfredo Jaramillo, Gustavo C. Buscaglia
The coupling of Reynolds and Rayleigh-Plesset equations has been used in several works to simulate lubricated devices considering cavitation. The numerical strategies proposed so f…
Continuous and discrete inf-sup conditions for surface incompressibility of a deformable continuum
Gustavo C. Buscaglia
Surface incompressibility, also called inextensibility, imposes a zero-surface-divergence constraint on the velocity of a closed deformable material surface. The well-posedness of…
A semi-implicit finite element method for viscous lipid membranes
Diego S. Rodrigues, Roberto F. Ausas, Fernando Mut +1
We propose a robust simulation method for phospholipid membranes. It is based on a mixed three-field formulation that accounts for tangential fluidity (Boussinesq-Scriven law), ben…
Parametric study of the interface behavior between two immiscible liquids flowing through a porous medium
Alejandro David Mariotti, Elena Brandaleze, Gustavo C. Buscaglia
When two immiscible liquids that coexist inside a porous medium are drained through an opening, a complex flow takes place in which the interface between the liquids moves, tilts a…
