Aquest treball s'estructura a partir d'una sèrie de reflexions que es contextualitza a partir de la voluntat de sistematitzar l'estudi de l'acció del vent sobre un edifici o una estructura. Després de diferents períodes ...
The analysis of the dynamic behaviour of rotating turbomachinery components is of relevant interest to avoid damages or fatigue problems in these parts. To determine the dynamic behaviour of a part of a structure it is ...
Hydraulic machines are faced with increasingly severe performance requirements. The need to design smaller and more powerful machines rotating at higher speeds in order to provide increasing efficiencies, has to face a ...
En los últimos años, los trabajos de investigación están muy motivados por todo aquello que contribuye a reducir el ruido emitido por los sistemas oleohidráulicos. Como ha sido demostrado por varios investigadores, el ...
The aim of this Ph.D. thesis, "Effects of flow control on flow past bluff bodies" is to study and analyzes the effects of Flow Control on various aspects and proverbs of flow past bluff bodies. Flow control techniques are ...
La experimentación y posterior modelización de los procesos de transporte y transferencia de calor y de masa en medios poroso saturados encuentra un gran número de dificultades que se derivan fundamentalmente de la ...
One of the challenges of the wind energy community today is to improve the existing background on the aerodynamic phenomena of a Horizontal Axis Wind Turbine (HAWT), the prediction of the wind speed distribution on the ...
Turbulence onset within an initially laminar flow is one of the most common phenomenon in Fluid Mechanics, yet is an open field of research. This is due to the many and diverse causes that can trigger turbulence, which ...
The main objective of this PhD thesis is the fluid dynamic characterization of the flow behind vortex generators (VG) as well as to investigate their influence in the separation of the boundary layer. CFD simulations have ...
The present doctoral thesis is about the numerical investigation simulated via using lattice Boltzmann method (LBM), the applications cover a large scale of subjects, including 1. Mathematical-physical equations A new ...
La tesis analiza el comportamiento anómalo de una servoválvula instalada en una máquina de electroerosión operando bajo ciertas condiciones de trabajo. <br/>En el primer capítulo de la tesis se describen una serie de ...
(English) This PhD mostly focuses in studding the flow around a square cylinder with an upstream splitter plate and considering different velocity ratios between the upper and lower inlet velocities. The PhD is based in ...
