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 ... -
Numerical Analysis of Viscoelastic Fluid Injection Processes
Conference report
Open AccessIn this work, a numerical framework aimed at simulating high-viscous and viscoelastic liquid injection processes is presented. The study of fluid injection with viscoelastic properties, such as synthetic polymers, is of ... -
Dynamic simulations of an absorption system with different working pairs at chiller and heat pump application
(Purdue University, 2021)
Conference report
Restricted access - publisher's policyThis work describes the dynamic simulation of a direct air-cooled single effect solar-driven absorption system and demonstrates the numerical results of the absorption system with different working pairs. The working pairs ... -
Experimental Analysis of a Draft Beer Ice Bank Machine
(Purdue University, 2021)
Conference report
Restricted access - publisher's policyIn a long-term established application as draft beer cooling and servicing machines, seems difficult to see any research application at first sight. However, this perspective change when one considers that the costs ... -
Preliminary assessment of a polygeneration system based on a concentrated photovoltaic thermal (CPVT) solar collectors
(Technishe Universität Berlin, 2021)
Conference report
Open AccessECOSun project has as main objective a cost reduction of electricity and heat co-generation via a Concentrated Photovoltaic/Thermal (CPV-T) system by applying low-cost materials and advanced industrial manufacturing methods. ... -
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 ... -
Optimization of the progress variable definition using a genetic algorithm for the combustion of complex fuels
(MCM, 2021)
Conference lecture
Open AccessIn this work counterflow diffusion flamelets of n-heptane and air are used at stable and unsteady extinguishing conditions for building a thermo-chemical database for Computational Fluid Dynamics (CFD) calculations. The ... -
High-fidelity simulations of the mixing and combustion of a technically premixed hydrogen flame
(MCM, 2021)
Conference lecture
Open AccessNumerical simulations are used here to obtain further understanding on the flashback mechanism of a technically premixed hydrogen flame operated in lean conditions. Recent work from the authors (Mira et al., 2020) showed ...
