In Diesel engines, the internal flow characteristics in the fuel injection nozzles, such as the
turbulence level and distribution, the cavitation pattern and the velocity profile affect significantly the air-fuel mixture ...
[EN] The ability to handle complex geometries is an important part of transient calculations; therefore, the need for fully automatic mesh generation capable of dealing with such geometries is quite demanded. In this paper ...
Perre, Patrick; Turner, Ian(Editorial Universitat Politècnica de València, 2018-09-07)
[EN] Fractional order derivatives provide useful alternatives to their integer order counterparts due to their ability to model memory and other properties of the porous medium, such as nonlocal behaviour. These phenomena ...
[EN] The spatial distribution of the neutron flux within the core of nuclear reactors is a key factor in nuclear safety. The easiest and fastest way to determine it is by solving the eigenvalue problem of the neutron ...

Heterogeneous nuclear reactors require numerical methods to solve the neutron diffusion equation (NDE)
to obtain the neutron flux distribution inside them, by discretizing the heterogeneous geometry in a set of
homogeneous ...

[ES] La Dinámica de Fluidos se encarga del estudio del movimiento de los mismos atendiendo a las causas que lo producen (gradientes de presión, componente tangencial de la fuerza gravitatoria, etc.). Las leyes que rigen ...
[EN] The use of mixed oxide (MOX) fuel to partially fill the cores of commercial light water reactors (LWRs) gives rise to a reduction of the radioactive waste and production of more energy. However, the use of MOX fuels ...
