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 ...
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 ...
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 ...
The energy efficiency assessment of high-pressure pneumatic circuits is the aim of this dissertation. From a historical perspective the past and cur- rent activities with regards to the energy saving conservation in pneumatic ...
The present thesis is undertaken to study the use of an aqueous solution of LiCl as a secondary refrigerant, due to its dehydrating properties, in those refrigeration applications that require mainly the air dehumidification ...
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 ...
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 ...
Space re-entry is a challenging endeavor due to the harsh thermo-chemical environment around the vehicle. Heat flux being the reference parameter for Thermal Protection System (TPS) design, the total energy transfer can ...
Nowadays, hydropower plays an essential role in the energy market. With the massive entrance of new renewable sources such as wind or solar power, hydropower is the only renewable generating source that can provide fast ...
Structural health monitoring has been defined as the acquisition, validation and analysis of technical data to facilitate life- cycle management decisions. It is the result of a convergent path from many previous existing ...
Hydropower plays a very important role in the world electricity generation nowadays. Hydropower is one type of renewable energy and is the only renewable energy source that can provide a wide range of power regulation with ...
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 ...
The future of hydropower is tied to the rapid increase of new renewable energies, such as photovoltaic and wind energy. With the growing share of intermittent electricity production, the operation of hydropower installations ...
