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 ... -
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. ... -
Synthesis and characterization of new fully bio-based poly(acylhydrazone) vanillin vitrimers
(2022)
Conference lecture
Open AccessNew acylhydrazone vitrimeric-type materials have been studied. These materials can be efficiently relaxed, without the addition of an external catalyst, through an exchange process that has been confirmed as imine metathesis, ... -
Design and smart control of sensors for optimal performance: a application to wind sensing in Mars
(2019)
Conference report
Open AccessSensor performance in terms of time response and sensitivity can be dramatically enhanced by operating sensors under what may be called a “constant state operation”. This means that any change in the sensor due to external ... -
Effect of hydrogen addition to methane-air jet flame based on Sandia flame D
(Scipedia, 2022)
Conference report
Open AccessThe present study investigates the effect of hydrogen addition to methane-air jet flame based on Sandia flame D. For this purpose, RANS simulations with a global four-step mechanism were first compared with other reduced ... -
New tools to motivate STEM students towards early-career self-management
(European Society for Engineering Education (SEFI), 2022)
Conference lecture
Open AccessThe Universitat Politècnica de Catalunya (UPC), the Czech Technical University in Prague (CTU) and the Universidade de Lisboa have recently undertaken the Engine4STEMers project, a joint initiative devoted to generating a ... -
On the conservation of primary and secondary properties in the simulation of multiphase flows
(Scipedia, 2022)
Conference report
Open AccessThe formulation of multiphase flows emanates from basic conservation laws: mass, momentum and energy. While these are embedded in the celebrated Navier-Stokes equations, none of these properties do necessarily hold when ... -
Numerical assessment of RANS and LES modelling in particle separation devices
(European Conference for AeroSpace Sciences (EUCASS), 2022)
Conference report
Open AccessIn the present work, the separation efficiency analysis on particle-laden flows in the framework of LES and RANS modelling for an Inertial Particle Separator (IPS) device has been presented. The comparison of LES and RANS ... -
Efficient strategies for solving the variable Poisson equation with large contrasts in the coefficients
(2022)
Conference report
Open AccessDiscrete versions of Poisson’s equation with large contrasts in the coefficients result in very ill-conditioned systems. Thus, its iterative solution represents a major challenge, for instance, in porous media and multiphase ...
