Analytical / Computational Approach to Liquid Spray Heating and Vaporization at Supercritical Pressures

Jorda Juanos, Albert; Sirignano, William (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] Our findings from two areas of background research will define an approach to the study of liquid spray heating and vaporization in gases at supercritical pressure: (i) vaporizing droplets at supercritical pressure ...
Comparación de nuevos conceptos en relación con el ciclo orgánico de Rankine para generación de energía

Giner Barrachina, Pablo María (Universitat Politècnica de València, 2020-05-13)

[ES] El cambio del ciclo de Rankine convencional al ciclo orgánico de Rankine con sus ventajas, nuevas aplicaciones y otro tipo de nuevos conceptos o variaciones que sufre el ciclo. Nuevos problemas que surgen de este ...
Energetic evaluation of a CO2 refrigeration plant working in supercritical and subcritical conditions

Sánchez, Daniel; Patiño, Jorge; Sanz Kock, Carlos; Llopis, Rodrigo; Cabello, Ramón; Torrella Alcaraz, Enrique (Elsevier, 2014-05)

Unlike other refrigerants, R744 (or carbon dioxide) has a very low critical temperature (30.98 C) which hampers working in subcritical conditions especially when the environment is used as a heat rejection sink. ...
Experimental investigation of Ethane and Propane injection under sub- and super-critical conditions

Vallee, Nathalie; Ribert, Guillaume; Blaisot, Jean-Bernard; Lisiecki, Denis (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] Studying a fluid flow under high-pressure conditions through reliable experiments is still nowadays a challenge. When the chamber pressure exceeds the critical pressure of working fluids the supercritical state of ...
New positions for an internal heat exchanger in a CO2 supercritical refrigeration plant. Experimental analysis and energetic evaluation

Sánchez, Daniel; Patiño, Jorge; Llopis, Rodrigo; Cabello, Ramón; Torrella Alcaraz, Enrique; Fuentes, Fernando Vicente (Elsevier, 2014-02-05)

IHX is probably, one of the most commonly alternative used to improve cooling capacity and COP in a CO2 refrigerating plant working in supercritical conditions. The classical position at gas-cooler exit has been analyzed ...
Supercritical and transcritical real-fluid mixing using the PC-SAFT EOS

Rodriguez, Carlos; Vidal, Alvaro; Koukouvinis, Phoevos; Gavaises, Manolis (Editorial Universitat Politècnica de València, 2017-07-28)

[EN] A numerical framework has been developed to simulate the mixing of supercritical and transcritical fluids using an equation of state based on statistical associating fluid theory. In a Diesel engine the liquid fuel ...
Techno-economic analysis of a hybrid CSP-PV plant including elctrical batteries

Ruiz Garrido, María (Universitat Politècnica de València, 2023-02-15)

[ES] La hibridación de la energía solar térmica de concentración (CSP) con la fotovoltaica ha cobrado fuerza e interés en el mercado debido a: el rápido descenso de los costes de las instalaciones fotovoltaicas; la necesidad ...
