On Preconditioning Variable Poisson Equation with Extreme Contrasts in the Coefficients
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessIt is well known that the solution by means of iterative methods of very ill-conditioned systems leads to very poor convergence rates. In this context, preconditioning becomes crucial in order to modify the spectrum of the ... -
Simulation of fluid-structure interaction and impact force on a reed valve
(2021)
Conference report
Open AccessThe cyclic impact force between a reed valve and the seat plate is the main reason of the valve failure in many thermo-technical devices as compressors, engines, etc. According to experimental observations the latter is ... -
Experimental and numerical analysis of reed valve movement in an impact fatigue test system and reciprocating compressors
(Purdue University, 2021)
Conference report
Restricted access - publisher's policyDuring operation of a reciprocating compressor, its flapper valve opens to allow the passage of gases and closes by striking against the valve impact plate. This reed valve movement and impact is repeated billions of times. ... -
Power electronics high performance air-cooled heat sinks integrating graphite based materials
(Purdue University, 2021)
Conference report
Restricted access - publisher's policyThe thermal management of the power electronics cooling in the aircraft is getting more attention in the recent years due to the progressive implementation of electrical systems, especially in the framework of the more ... -
Subgrid-Scale Model Based on the Invariants of the Gradient Model Tensor
(2021)
Conference report
Open AccessThe incompressible Navier-Stokes equations stand as the best mathematical model for turbulent flows. However, direct numerical simulations at high Reynolds numbers are not yet feasible because the convective term produces ... -
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. ... -
Surface tension and contact angle measurement of LiBr and Carrol solution
(Technishe Universität Berlin, 2021)
Conference report
Open AccessThe surface tension and contact angle play a relevant role in the heat and mass transfer for the absorption system working pairs. However, LiBr aqueous solution surface tension/contact angle studies are limited and for ... -
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 ...
