A symmetry-preserving second-order time-accurate PISO-based method
(Elsevier, 2021-07-15)
Article
Restricted access - publisher's policyA new conservative symmetry-preserving second-order time-accurate PISO-based pressure-velocity coupling for solving the incompressible Navier-Stokes equations on unstructured collocated grids is presented in this paper. ... -
Development of a reduced order model of solar heat gains prediction
(2020-12-01)
Article
Open AccessThe aim of this study was to elaborate and validate a reduced order model able to forecast solar heat gains as a function of the architectural parameters that determine the solar heat gains. The study focused on office ... -
A comprehensive simulation tool for adsorption-based solar-cooled buildings. Control strategy based on variable cycle duration
(2021-01-15)
Article
Restricted access - publisher's policyAdsorption cooling systems (ACS) may contribute towards a sustainable way of satisfying the increasing cooling demand, as they utilize solar thermal energy and employ non-ozone-depleting substances. Apart from the intrinsic ... -
A scalable framework for the partitioned solution of fluid-structure interaction problems
(Springer, 2020-08)
Article
Open AccessIn this work, we present a scalable and efficient parallel solver for the partitioned solution of fluid–structure interaction problems through multi-code coupling. Two instances of an in-house parallel software, TermoFluids, ... -
On the feasibility of affordable high-fidelity CFD simulations for indoor environment design and control
(2020-10-15)
Article
Restricted access - publisher's policyComputational fluid dynamics (CFD) is a reliable tool for indoor environmental applications. However, accurate CFD simulations require large computational resources, whereas significant cost reduction can lead to unreliable ... -
A hierarchical parallel implementation for heterogeneous computing. Application to algebra-based CFD simulations on hybrid supercomputers
(Elsevier, 2021-01)
Article
Restricted access - publisher's policyThe quest for new portable implementations of simulation algorithms is motivated by the increasing variety of computing architectures. Moreover, the hybridization of high-performance computing systems imposes additional ... -
Tetrahedral adaptive mesh refinement for two-phase flows using conservative level-set method
(2021-02)
Article
Open AccessIn this article, we describe a parallel adaptive mesh refinement strategy for two-phase flows using tetrahedral meshes. The proposed methodology consists of combining a conservative level-set method with tetrahedral adaptive ... -
Transient model for the development of an air-cooled LiBr-H2O absorption chiller based on heat and mass transfer empirical correlations
(Elsevier, 2020-12)
Article
Restricted access - publisher's policyThis work describes transient numerical modeling of a direct air-cooled,single-effect absorption chiller. The model is lumped parametric based on transient mass, momentum, and energy balances, applied to the internal ... -
Fluid-structure interaction based on HPC multicode coupling
(2018)
Article
Restricted access - publisher's policyThe fluid-structure interaction (FSI) problem has received great attention in the last few years, mainly because it is present in many physical systems, industrial applications, and almost every biological system. In the ... -
On a Proper Tensor-Diffusivity Model for Large-Eddy Simulation of Buoyancy-Driven Turbulence
(Springer, 2020-03-26)
Article
Open AccessIn this work, we aim to shed light to the following research question: can we find a nonlinear tensorial subgrid-scale (SGS) heat flux model with good physical and numerical properties, such that we can obtain satisfactory ... -
Flow topology dynamics in a three-dimensional phase space for turbulent Rayleigh-Bénard convection
(2020-02-28)
Article
