Temperature gradient effects on a turbulent channel flow at Ret=400
(Begell House, 2023)
Conference report
Restricted access - publisher's policyA direct numerical simulation (DNS) of an asymmetrically heated turbulent channel flow has been performed to study the temperature gradient effects on the turbulence. The case has been set as a compressible flow with ... -
Numerical study of the flow past a three-element high-lift airfoil at different angles of attack
(2023)
Conference lecture
Open AccessA parametric study of the 30p30n three-element high-lift airfoil is conducted by changing the angle of attack at α = 5, 9 and 23◦ at a constant Reynolds number of Rec = 750, 000. Computational predictions are performed ... -
Turbulent statistics and coherent structures in an asymmetrically heated channel flow
(2023)
Conference report
Open AccessA compressible direct numerical simulation (DNS) has been conducted to analyze the behavior of a fully developed turbulent channel flow. The problem has been set at mean friction Reynolds number Ret m = 400 submitted to a ... -
Experimental testing of a solar thermal collector with composite TIM of plastic Honeycomb and silica aerogel polyurethane containers
(International Solar Energy Society, 2022)
Conference report
Restricted access - publisher's policyA new proposal of high performance flat plate solar thermal collector (FPC) based on Transparent Insulation Materials (TIM) combining silica aerogel contained in insulation containers with plastic honeycomb is evaluated ... -
Numerical modeling and simulation comparisons of a cost efficient novel CPVT Solar Collector
(International Solar Energy Society, 2022)
Conference report
Restricted access - publisher's policyIn this work, the simulation of a Concentrated PhotoVoltaic Thermal (CPVT) solar collector system has been done by means of Finite Volume Method. The system consists of a parabolic collector, which concentrates solar ... -
Self-induced large-scale motions in a three-dimensional diffuser
(Springer, 2023-09-14)
Article
Open AccessA direct numerical simulation of a three-dimensional diffuser at Reynolds number Re = 10,000 (based on inlet bulk velocity) has been performed using a low-dissipation finite element code. The geometry chosen for this work ... -
Structural design of CANs with fine-tunable relaxation properties: a theoretical framework based on network structure and kinetics modeling
(American Chemical Society, 2023-06-23)
Article
Open AccessIn this work, we present a model capable of reproducing the stress relaxation dynamics of a wide range of relaxation processes in covalent adaptable networks (CANs) produced by stepwise polymerization. The proposed model ... -
Simulation of flash floods in ungauged basins using post-event surveys and numerical modelling
(John Wiley & sons, 2015-12-01)
Article
Restricted access - publisher's policyThe hydrological and hydraulic processes of the flash flood that affected Atrani village (Amalfi Coast of Southern Italy) on 9 September 2010 are analysed using post-flood surveys and numerical modelling. Observations in ... -
CFD studies and experimental validation of the convective heat transfer coefficient in non-fully developed flows applied to conventional geometries used in particle accelerators
(Joint Accelerator Conferences Website (JACoW), 2023)
Conference report
Open AccessIn the field of Particle Accelerators engineering, the design of the cooling channels of its components has been extensively based on experimental correlations for the calculation of convective heat transfer coefficients. ... -
Aspect ratio influence on the vortex induced vibrations of a pivoted finite height cylinder at low Reynolds number
(2023-08-10)
Article
Open AccessThe effect of the aspect ratio on the vortex induced vibrations (VIV) of a pivoted finite length circular cylinder is investigated. A fixed value of the Reynolds number Re = 100 with four values of the aspect ratio ... -
Hybrid computation of the aerodynamic noise radiated by the wake of a subsonic cylinder
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-21)
Article
Open AccessThe noise radiated by the flow around a cylinder in the subcritical regime at 𝑅𝑒𝐷=1×104 and at a subsonic Mach number of 𝑀=0.5 is here studied. The aerodynamic sound radiated by a cylinder has been studied with a ... -
Recyclable dual-curing thiol-isocyanate-epoxy vitrimers with sequential relaxation profiles
(Elsevier, 2023-09-11)
Article
Open AccessTwo series of poly(thiourethane)s-poly(thiol-epoxy) hybrids were prepared from dual-curing, stoichiometric thiol:isocyanate:epoxy mixtures. 1-methylimidazole (MI) was used as initiator for the thiol-isocyanate and thiol-epoxy ...
