A numerical scheme for two-scale phase-field models in porous media

Bastidas, Manuela; Sharmin, Sohely; Bringedal, Carina; Pop, Sorin (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] We consider the flow of two immiscible fluid phases in a porous medium. At the scale of pores, the two fluid phases are separated by interfaces that are transported by the flow. Furthermore, the surface tension at ...
Derivation of the method of characteristics for the fluid dynamic solution of flow advection along porous wall channels

Desantes Fernández, José Mª; Serrano Cruz, José Ramón; Arnau Martínez, Francisco José; Piqueras Cabrera, Pedro (Elsevier, 2012-07)

This paper describes in detail a novel formulation of the method of characteristics for its application to solve one-dimensional compressible unsteady non-homentropic flow advected along porous wall channels. In particular, ...
Estudio estratégico sobre la aplicabilidad del Método Lattice-Boltzmann como herramienta de computación de altas prestaciones en motores de combustión interna alternativos

García Galache, José Pedro (Universitat Politècnica de València, 2014-11-24)

[EN] The final master thesis begins putting in place the LBM method among the most used CFD techniques. In following sections it is deeply explained how LBM internally works. After understanding, the main advantages and ...
Experimental study of the flame propagation in the porous media for Hydrogen-Ammonia blended fuels

Aguilar Cervera, Juan (Universitat Politècnica de València, 2020-10-29)

[ES] En los últimos años ha aumentado la preocupación por el cambio climático. El uso de combustibles fósiles está provocando un aumento en la temperatura promedio global del planeta. Una alternativa adecuada a estos ...
Experimental theoretical methodology for determination of inertial pressure drop distribution and pore structure properties in wall-flow diesel particulate filters (DPFs)

Payri González, Francisco; Broatch Jacobi, Jaime Alberto; Serrano Cruz, José Ramón; Piqueras Cabrera, Pedro (Elsevier, 2011-12)

Wall-flow particulate filters have been placed as a standard technology for Diesel engines because of the increasing restrictions to soot emissions. The inclusion of this system within the exhaust line requires the development ...
Extraordinary absorption of sound in porous lamella-crystals

Christensen, Johan; Romero García, Vicente; Picó Vila, Rubén; Cebrecos Ruiz, Alejandro; Garcia de Abajo, Francisco Javier; Mortensen, N. A.; Willatzen, M.; Sánchez Morcillo, Víctor José (Nature Publishing Group: Open Access Journals - Option C, 2014-04-14)

We present the design of a structured material supporting complete absorption of sound with a broadband response and functional for any direction of incident radiation. The structure which is fabricated out of porous ...
Flujos incompresibles en medios porosos: Formulación y simulación

Escrig Beltrán, Carlos (Universitat Politècnica de València, 2021-12-01)

[ES] El objetivo del trabajo es implementar un método de penalización de Brinkman (BPM) en un software de dinámica de fluidos computacional (CFD) utilizando un solver de volúmenes finitos. El BPM fue originalmente propuesto ...
Heat and fluid flow past a vertical plate with lateral mass flux in a porous medium

Cortell Bataller, Rafael (Inderscience, 2012)

[EN] A numerical analysis for free convection boundary layers along a permeable vertical flat surface with prescribed power-law temperature distribution T w(x) = T¿ + Ax k at y = 0 embedded in a fluid-saturated porous ...
Heat Transfer in a Fluid Through a Porous Medium over a Permeable Stretching Surface with Thermal Radiation and Variable Thermal Conductivity

Cortell Bataller, Rafael (Wiley, 2012)

This paper treats about the flow and heat transfer of a viscous incompressible fluid in a porous medium over a permeable stretching surface taking into account thermal radiation and the variation of the thermal conductivity ...
Hydraulic performance analysis for homogeneous mound breakwaters: Application of dimensional analysis and a new experimental technique

Díaz-Carrasco, Pilar (Elsevier, 2023-10-15)

[EN] The main objective of this study is to apply the methodology proposed by Diaz-Carrasco et al. (2020), based on the dimensional analysis and a new experimental technique, to estimate and study the wave energy transformation ...
Neural Network calibration method for VARANS models to simulate wave-coastal structures interaction.

Díaz-Carrasco, Pilar; Molines, Jorge; GÓMEZ-MARTÍN, M. ESTHER; Medina, Josep R. (Elsevier, 2024-03)

[EN] This study develops a calibration method for the porous media to properly model the interaction between waves and coastal structures using VARANS models. The proposed method estimates the porosity, np, and the optimum ...
Optimum configuration for accurate simulations of chaotic porous media with Lattice Boltzmann Methods considering boundary conditions, lattice spacing and domain size

Gil, A.; García Galache, José Pedro; Godenschwager, C.; Rüde. U. (Elsevier, 2017)
