Análisis CFD de transferencia de calor por convección natural para integración de dispositivos termoeléctricos

Dombrovsky, Artem (2022-07-07)

[ES]En la actualidad el desarrollo de metodolog´ıas para el aprovechamiento energ´etico tiene un creciente inter´es en industrias de cualquier tipo, incluyendo la aeroespacial. Este inter´es se debe a la necesidad de ...
Development and validation of a radial turbine efficiency and mass flow model at design and off-design conditions

Serrano Cruz, José Ramón; Arnau Martínez, Francisco José; García-Cuevas González, Luis Miguel; Dombrovsky, Artem; Tartoussi, H. (Elsevier, 2016-11-15)

Turbine performance at extreme off-design conditions is growing in importance for properly computing turbocharged reciprocating internal combustion engines behaviour during urban driving conditions at current and future ...
Experimental analysis and one-dimensional modeling of heat transfer phenomena in turbochargers for internal combustion engines

Dombrovsky, Artem (Universitat Politècnica de València, 2015-06-16)

[EN] Nowadays, the regulation of pollutant emissions of reciprocating internal combustion engines becomes more and more restrictive. One of the main strategies to reduce those emissions is the reduction of engine volume ...
External heat losses in small turbochargers: Model and experiments

Payri González, Francisco; Olmeda, P.; Arnau Martínez, Francisco José; Dombrovsky, Artem; Smith, Les (Elsevier, 2014-07-15)

[EN] The behavior of small turbochargers is deeply affected by heat transfer phenomena. The external heat losses of these machines are studied and a simplified model that takes into account both radiation and convective ...
General Procedure for the Determination of Heat Transfer Properties in Small Automotive Turbochargers

Serrano Cruz, José Ramón; Olmeda González, Pablo Cesar; Arnau Martínez, Francisco José; Dombrovsky, Artem (SAE International, 2014-10)

These days many research efforts on internal combustion engines are centred on optimising turbocharger matching and performance on the engine. In the last years a number of studies have pointed out the strong effect on ...
Synthesis of the 1D modelling of turbochargers and its effects on engine performance prediction

Dombrovsky, Artem (Universitat Politècnica de València, 2017-06-05)

Low fuel consumption is one of the main requirement for current internal combustion engines for passenger car applications. One of the most used strategies to achieve this goal is to use downsized engines (smaller engines ...
Turbocharger heat transfer and mechanical losses influence in predicting engines performance by using one-dimensional simulation codes

Serrano Cruz, José Ramón; Olmeda González, Pablo Cesar; Arnau Martínez, Francisco José; Dombrovsky, Artem; Smith, Les (Elsevier, 2015-06-15)

The exhaust energy can represent up to 40% of the fuel chemical energy in turbocharged internal combustion engines. In order to calculate properly the available energy of the exhaust gases, a critical parameter is the ...
