Aerothermal Characterisation of Surface Heat Exchangers for Turbofans

Felgueroso Rodríguez, Andrés (Universitat Politècnica de València, 2023-09-04)

[ES] En un presente marcado por la continua lucha contra la contaminación y el cambio climático, la investigación en mejoras tecnológicas que permitan una transición aceptable para la sociedad hacia un futuro más ecológico ...
Application of Magnetocaloric Heat Pumps in Mobile Air-Conditioning

Torregrosa-Jaime, Barbara; Vasile-Müller, Carmen; Risser, Michel; Muller, Christiane; Corberán, José M.; Payá Herrero, J. (SAE (Society of Automotive Engineers) International, 2013)

[EN] Air-conditioning (AC) is an important sub-system in electric vehicles (EVs). AC is responsible for the highest energy consumption among all the auxiliary systems. As the energy is delivered by the batteries, the power ...
Desarrollo de una bomba de calor doméstica que usa propano como fluido de trabajo

López Juárez, Emilio (Universitat Politècnica de València, 2023-09-10)

[ES] Las regulaciones medioambientales imponen el uso de refrigerantes con cada vez menor Poder de Calentamiento Atmosférico (PCA), y obligan a que la búsqueda de refrigerantes alternativos a los actuales sea una necesidad ...
Development and validation of a finite element model for water - CO2 coaxial gas-coolers

Sanchez, D.; Cabello, R.; Llopis, R.; Torrella Alcaraz, Enrique (Elsevier, 2012-05)

The gas-cooler heat exchanger is a characteristic device of the refrigeration plants that use CO2 as the working fluid in transcritical conditions. The proper gas-cooler sizing, allows getting the maximum effectiveness in ...
Diseño, analisis y optimización de un modelo digital del flujo de producción industrial

Mora Carrión, Sergio (Universitat Politècnica de València, 2021-10-27)

[ES] El alcance de este proyecto es construir un modelo digital de un flujo de producción utilizando elSoftware de Siemens "Plant Simulation". Cada módulo, p. Ej. línea de prensa o estación de montaje, se construirá con ...
Energetic evaluation of an internal heat exchanger in a CO2 transcritical refrigeration plant using experimental data

Torrella Alcaraz, Enrique; Sanchez, D.; Llopis, R.; Cabello, R. (ELSEVIER SCI LTD, 2011)

[EN] The performance of an Internal Heat Exchanger (IHX) operating in a CO 2 transcritical refrigeration plant is analysed, from an energetic point of view, in this work. The evaluation is based on experimental data by ...
Experimental aerothermal characterization of surface air-cooled oil coolers for turbofan engines

Broatch, A.; Olmeda, P.; GARCIA TISCAR, JORGE; Felgueroso-Rodríguez, Andrés; Chávez-Modena, M.; González, L. M.; Gelain, M.; Couilleaux, A. (Elsevier, 2022-07)

[EN] Thermal management is a major challenge for new generation turbofan aero-engines. One of the most promising heat exchangers are the so-called surface air-cooled oil coolers (SACOCs). In this study, an experimental ...
Experimental and numerical methodology for the aero-thermal analysis of a SACOC heat exchanger

Chávez-Modena, Miguel; Miguel González, Leo; Valero, Eusebio; Broatch, A.; García-Tíscar, Jorge; Felgueroso, Andrés (Elsevier, 2023-01-25)

[EN] Surface air-cooled oil coolers (SACOC) are being used in the aerospace industry. This device is a passive heat exchanger used to dissipate a large amount of heat from the oil circuit of a turbofan engine to its secondary ...
Heat transfer modelling in honeycomb wall-flow diesel particulate filters

Galindo, José; Serrano Cruz, José Ramón; Piqueras, P.; García Afonso, Óscar (Elsevier, 2012-07)

Heat transfer in wall-flow monoliths has gained in interest because of the widespread adoption of these systems by automotive industry to fulfil soot emission regulations and the importance of heat exchange on the regeneration ...
Impact of classical assumptions in modelling a microchannel gas cooler

Martínez-Ballester, Santiago; Corberán, José M.; Gonzálvez-Maciá, José; Domanski, Piotr A. (Elsevier, 2011)

[EN] Most of the current air-to-refrigerant heat exchanger models use the classic ¿-NTU approach, or some of its assumptions. These models do not account for longitudinal heat conduction in the tube and the fin, and the ...
Improving parameter estimates obtained from thermal response tests: Effect of ambient air temperature variations

Bandos, Tetyana; Montero Reguera, Álvaro Enrique; Fernández de Córdoba Castellá, Pedro José; Urchueguía Schölzel, Javier Fermín (Elsevier, 2011-06)

[EN] This paper presents a method of subtracting the effect of atmospheric conditions from thermal response test (TRT) estimates by using data on the ambient air temperature. The method assesses effective ground thermal ...
