[EN] Ideal models provide the simplest way to reproduce internal combustion engine (ICE) cycles, but they usually do not represent with sufficient accuracy the actual behaviour of an ICE. A suitable alternative for research ...

Combustion diagnosis based on in-cylinder pressure signals as well as 0D thermodynamic modelling, are widely used to study and optimize the combustion in reciprocating engines. Both approaches share some uncertainties ...

[EN] Mild thermal treatments could be considered a feasible technique with which to improve the texture of dry-cured ham. This study explores the feasibility of using power ultrasound (PuS) to intensify heat transfer during ...

Friction and heat transfer in metal forming simulations are usually restricted by software to be interface constants, a situation not reflected by the mechanics of real manufacturing processes. A better simulation approach ...

Emission legislation together with the need of more fuel-efficient engines have driven the development of promising combustion concepts in compression ignition (CI) engines. Most of them, lead toward a lean and low temperature ...

[EN] This paper firstly presents a comprehensive minichannel evaporator model (MCHX-1D-MB) based on fin theory coupled with the moving boundary technique along fin height. To validate the presented model, experimental data ...

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 ...

[EN] Direct Numerical Simulations of turbulent heat transfer in a channel flow are presented for three different Reynolds numbers, namely Re-tau = 500, 1000 and 2000. Medium and low values of the molecular Prandtl number ...

[EN] During the last years, the growing awareness about the impacts of climate change lead to an increase in the importance of the efficiency over other criteria in the design of internal combustion engines. In this ...

[ES] El presente trabajo consiste en el ensayo completo de un turbocompresor, y la utilización de los datos experimentales obtenidos en la validación de modelos existentes. El proyecto cuenta con dos ensayos bien ...
