Resuspension and control of reservoir sediments by surface waves and point absorbers
(International Association for Hydro-Environment Engineering and Research (IAHR), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialThis work is intended to investigate the deliberate generation of mild waves on the surface of reservoirs and the use of a farm of point absorbers, floating buoys or akin technology, to convert the energy transported by ... -
Three dimensional analysis of ahmed body aerodynamic performance enhancement using steady suction and blowing flow control techniques
(2018)
Text en actes de congrés
Accés restringit per política de l'editorialAerodynamic drag reduction plays a vital role in the reduction of automobiles fuel consumption. Boundary layer physics and its intricate mechanisms that result in flow separation are to be understood and manipulated using ... -
Three dimensional structures of flow through a square cylinder with an upstream splitter plate and for several velo city ratios
(2018)
Text en actes de congrés
Accés restringit per política de l'editorialIn the present paper, three-dimensional Fluid structures and wake characteristics are evaluated for a square cylinder with an upstream splitter plate. The splitter plate divides the incoming flow in two streams, the ... -
Experimental Investigation of the Cavitation Effects on the Heat Generation in a Closed Loop Pumping System
(2018)

Experimental validation and modelling of electromagnetic kinetic harvester for oceans drifters
(2017)
Text en actes de congrés
Accés obertHarvesting the mechanical energy of ocean motion are finding different applications for offshore exploration and ocean monitoring. Because of the very low and varying frequency, from 0.1Hz to 2Hz, harvesting this energy ... -
Enviromental patterns and intermittent cascades
(2017)
Text en actes de congrés
Accés obertReal environmental flows are non-homogeneous, of fundamental interest is to determine and quantify turbulent diffusion from the available conditions of the flow, because the role of buoyancy and rotation modify the flow ... -
Detection and analysis of part load and full load instabilities in a real Francis turbine prototype
(Institute of Physics (IOP), 2017)
Text en actes de congrés
Accés obertFrancis turbines operate in many cases out of its best effici ency point, in order to regulate their output power according to the instantaneous ener gy demand of the grid. Therefore, it is of paramount importance to analyse ...
