Kinetic-energy- and pressure-equilibrium-preserving schemes for real-gas turbulence in the transcritical regime
(2023-09-04)
Article
Accés obertNumerical simulations of compressible turbulent flows governed by real-gas equations of state, such as high-pressure transcritical flows, are strongly susceptible to instabilities. In addition to the inherent multi-scale ... -
A review of thermal exposure and fire spread mechanisms in large outdoor fires and the built environment
(2023-10)
Article
Accés obertDue to socio-economic and climatic changes around the world, large outdoor fires in the built environment have become one of the global issues that threaten billions of people. The devastating effects of them are indicative ... -
Thermodynamics-informed neural network for recovering supercritical fluid thermophysical information from turbulent velocity data
(Elsevier, 2023-11)
Article
Accés obertRecent research has highlighted the potential of supercritical fluids under high-pressure transcritical conditions to achieve microconfined turbulence as a result of the thermophysical properties they exhibit in the vicinity ... -
Time-dependent 2-D model for transport of species analysis in electrodialysis: concentration profiles and fluxes
(2023-07-05)
Article
Accés restringit per política de l'editorialElectrodialysis (ED) is a separation process that uses an electric field to selectively transport ions through ion exchange membranes. To further advance the technology and bring it to an industrial scale, modeling ED and ... -
Dimensionality reduction of non-buoyant microconfined high-pressure transcritical fluid turbulence
(2023-06-02)
Article
Accés obertThis work utilizes a novel data-driven methodology to reduce the dimensionality of non-buoyant microconfined high-pressure transcritical fluid turbulence. Classical dimensional analysis techniques are limited by the ... -
Multiscale flow topologies in microconfined high-pressure transcritical fluid turbulence
(2023-05-30)
Article
Accés obertThe topology of multiscale turbulent motions in a high-pressure transcritical channel flow is studied using direct numerical simulations. In particular, the system analyzed corresponds to high-pressure (P/Pc=2) microconfined ... -
Thermal convection in rotating spherical shells: Temperature-dependent internal heat generation using the example of triple-a burning in neutron stars
(2018-12-10)
Article
Accés obertWe present an extensive study of Boussinesq thermal convection including a temperature-dependent internal heating source, based on numerical three-dimensional simulations. The temperature dependence mimics triple-a nuclear ... -
Continuation and stability of rotating waves in the magnetized spherical Couette system: secondary transitions and multistability
(2018-12)
Article
Accés obertRotating waves (RW) bifurcating from the axisymmetric basic magnetized spherical Couette (MSC) flow are computed by means of Newton–Krylov continuation techniques for periodic orbits. In addition, their stability is analysed ... -
RHEA: an open-source Reproducible Hybrid-architecture flow solver Engineered for Academia
(The Open Journal, 2023-01-13)
Article
Accés obertThe study of complex multiscale flows (Groen et al., 2014), like for example the motion of small-scale turbulent eddies over large aerodynamic structures (Jofre & Doostan, 2022), microconfined high-pressure supercritical ... -
High dimensional tori and chaotic and intermittent transients in magnetohydrodynamic Couette flows
(2023-04)
Article
Accés obertThe magnetised spherical Couette (MSC) problem, a three dimensional magnetohydrodynamic paradigmatic model in geo- and astrophysics, is considered to investigate bifurcations to high-dimensional invariant tori and chaotic ... -

Modelling mass transfer from a packed bed by fluid extraction
(2022-06-01)
Article
Accés obertA mathematical model describing the erosion or leaching of a solid material by a flowing fluid in a column is developed. This involves an advection-diffusion equation coupled to a linear kinetic reaction describing the ...
