(Date of defense: 26-11-2013)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 ...
-
(Date of defense: 31-07-2014)Positive displacements pumps, as currently designed, produce significant flow pulsations that result in pressure pulsations. These pulsations contribute to the global noise generated by the installation. Moreover, they ...
-
(Date of defense: 10-09-2015)In this thesis a study was performed to obtain a model of artificial neural network that is able to predict the flow behavior of steel under hot deformation conditions. The hot compression tests are performed on two types ...
-
(Date of defense: 22-03-2013)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 ...
-
(Date of defense: 15-02-2013)A les turbomàquines pot haver una forta interacció entre els àleps del rodet i les directrius del difusor que afecten la dinàmica del flux i el rendiment estructural de les màquines. Aquest fenomen s’anomena interacció ...
-
(Date of defense: 26-02-2013)The dynamic response of any structure submerged in water is significantly modified by the effect of added mass. The inertia of the fluid that the body must accelerate during its vibrational motion decreases its natural ...
-
(Date of defense: 27-04-2012)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 ...
-
(Date of defense: 28-03-2014)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 ...
-
(Date of defense: 23-11-2016)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 ...
-
(Date of defense: 02-06-2017)The weight of electric and electronic components of cars has been uninterruptedly increasing through the last decades, and thus the weight of their wiring harnesses. This fact has awakened the interest of car manufacturers ...
