Experimental evidence of inter-blade cavitation vortex development in Francis turbines at deep part load condition

François Avellan, Arthur Tristan Favrel, Keita Yamamoto

Francis turbines are subject to various types of cavitation flow depending on the operating condition. To enable a smooth integration of the renewable energy sources, hydraulic machines are now increasingly required to extend their operating range, especia ...

A method for taking into account seasonal storage in a district energy system optimisation problem

François Maréchal, Jessen Page, Jean-Loup Sylvain Robineau

In this work, a method for taking into account seasonal storage in an energy optimisation problem is developed. A master-slave optimisation procedure is applied, in which the master optimisation is an evolutionary algorithm, while the slave optimisation is ...

Robust and Gain-Scheduled PID Controller Design for Condensing Boilers by Linear Programming

Alireza Karimi

This paper addresses the water temperature control in condensing domestic boilers. The main challenge of this process under the controller design perspective is the fact that the dynamics of condensing boilers are strongly affected by the demanded water fl ...

Water: A key resource in energy production

Christoph Frei

Water and energy are the key resources required for both economic and population growth, and yet both are increasingly scarce. The distribution of water takes large amounts of energy, while the production of energy requires large amounts of water in proces ...

Modeling and Dynamic Management of 3D Multicore Systems with Liquid Cooling

David Atienza Alonso, José Luis Ayala Rodrigo

Three-dimensional (3D) circuits reduce communication delay in multicore SoCs, and enable efficient integration of cores, memories, sensors, and RF devices. However, vertical integration of layers exacerbates the reliability and thermal problems, and coolin ...
