Flow-induced vibrations of a rigid prism with an open semicircular cross section, supported elastically, were experimentally studied in a free-surface water channel. The objective of the study was to explore the prism's potential to promote flow mixing in its wake and simultaneously harvest mechanical energy from the incoming flow. The mechanical d...

We study the Cauchy problem for the Einstein-Boltzmann system with soft potentials in a cosmological setting. We assume the Bianchi I symmetry to describe a spatially homogeneous, but anisotropic universe and consider a cosmological constant Λ>0 to describe an accelerated expansion of the universe. For the Boltzmann equation we introduce a new weig...

In this paper, we present the application of a special soil resistivity model, the Exponentially Graded Multilayered Soil model, to the interpretation of Borehole Resistivity Logging surveys. The model, which was recently introduced by the authors, offers an alternative to the interpretation provided by constant resistivity layer models. The model ...
Three strategies for enhancing the melting rate of phase change materials (PCMs) are analyzed numerically: natural convection, thermocapillary convection, and variations in container geometry motivated by the natural shape of the advancing solid/liquid front. An enthalpy-porosity formulation of the Navier-Stokes equations is used to model the melti...
Presentaciones personales (handout) de la asignatura Mecánica Física (1302), del grado en Fundamentos de Arquitectura. Esta presentación contiene mi visión de la asignatura y, además, un material adicional que normalmente no sería utilizado en un curso, pero que es útil como ampliación.
Real-time weighing plays a crucial role in various applications in the road infrastructure field, such as pavement design, pavement monitoring systems, and the development of digital twins. Innovative sensing technologies offer solutions to the limitations of traditional sensors, enhancing durability and cost-effectiveness. Current research on self...
The potential for sloshing reduction of passive, moving baffles with translational motion constrained by springs is investigated numerically in partially filled containers. Simulations are based on the level-set formulation, considering water as the liquid under study and a baffle made of aluminum; this selection allows for direct validation of the...
