A small component of ECCD exists when heating off-axis with no toroidal injection due to the field helicity. The sign of the ECCD will change depending on the absorption location in a poloidal plane, the beam injection relative to delB(vac), and the direct ...
This paper aims to illustrate a new holistic modeling environment through a case study implementing a district heating system to supply four groups of users identified in the city of Tokyo. The holistic modeling environment, called DOME (Distributed Object ...
In this work, a parametric study is done with computational methods for groundwater flow and heat transport in order to describe the dominant physical phenomena in an Aquifer Thermal Energy Storage (ATES). Optimum operating conditions and geological parame ...
Although heat pump based district heating is often an obvious solution from an energy standpoint, adapting the delivery temperature to the most exigent users is detrimental to overall system performance. This pitfall can be avoided with a centralized plant ...
The subject of this project is to develop a high performance air water heat pump which is able to be introducted in the retrofit market. The system requirements of this market are heating temperatures of 65°C, at ambient temperatures descending until -12°C ...
Many chem. reactions, like the dehydrogenation of gaseous methanol to formaldehyde, require fast heating and cooling of the gases to control precisely the residence time at the reaction temp. (on the order of hundreds of ms) to minimize consecutive reactio ...
Transport phenomena in tokamak plasmas strongly limit the particle and energy confinement and represent a crucial obstacle to controlled thermonuclear fusion. Within the vast framework of transport studies, three topics have been tackled in the present the ...
Among the structure independent approaches of process integration, pinch technology has been shown for continuous processes to be extremely powerful to develop energy efficient processes and enhance synergic effects within and between processes. The earlie ...
Although heat pump based district heating is often an obvious solution from an energy standpoint, adapting the delivery temperature to the most exigent users is detrimental to overall system performance. This pitfall can be avoided with a centralized plant ...
The paper describes a predictive and adaptive heating controller, using artificial neural networks to allow the adaptation of the control model to the real conditions (climate, building characteristics, user's behaviour). The controller algorithm has been ...
