Full steady-state operation in Tore Supra

Plasma Physics and Controlled Fusion, 1996
In order to produce fully non-inductive, lower hybrid (LH) driven discharges in a systematic and reproducible manner, new operation modes have been studied on the superconducting Tore Supra tokamak. To cope with some uncertainties in the LH current drive efficiency (e.g.

Steady-state operability characteristics of idealized reactors

Chemical Engineering Science, 2001
Abstract Operability analysis is one of the bridges that links process design and control. In this paper, we analyze the steady-state operability characteristics of classical reactors (CSTR and PFR) in the framework of Vinson and Georgakis (DYCOPS-5, Fifth IFAC Symposium on Dynamics and Control of Process Systems, 1998, pp. 700–709; J. Proc.

Optimization of non‐steady‐state operation of reactors

The Canadian Journal of Chemical Engineering, 1989
AbstractNon‐steady‐state operation of reactors is approached from the optimal control point of view. To find the best type of input, dynamic programming is used. The results show that for some systems, the optimal input is oscillatory in nature as has been found experimentally by others.

Multiple roll systems: Steady‐state operation

AIChE Journal, 1995
AbstractRoll coaters for applying liquid coating to continuous strip or web are, with some two‐roll exceptions, systems of three or more rolls in which liquid passes through two or more gaps or nips between rolls. Yet most of the literature on roll coating is devoted to some of the 11 distinct flows in individual gaps or nips. This article analyzes how

LHD diagnostics towards steady state operation

The 30th International Conference on Plasma Science, 2003. ICOPS 2003. IEEE Conference Record - Abstracts., 2003
Summary form only given, as follows. The Large Helical Device, LHD, is the world largest helical system having all superconducting coils. After completion of LHD in 1998, 6 experimental campaigns have been carried out successfully. The maximum stored energy, electron temperature, and beta value are 1.2 MJ, 10 keV, 3.2 %, respectively.

Steady state voltage instability operations perspective

IEEE Transactions on Power Systems, 1990
This work reviews the basic theory of steady-state voltage instability; provides a physical interpretation of steady-state voltage instability; identifies some of the problems operators are presently experiencing; and gives simple procedures which can be used to determine system margin on a real-time basis.

Technical Issues With Steady-State Operation in KSTAR

IEEE Transactions on Plasma Science, 2018
Achieving and sustaining long pulse and ultimately steady-state operation of a fusion reactor in terms of physics and engineering parameters beyond transient period is essentially one of key requirements in present non Deuterium Tritium (DT) discharge tokamaks.

Thermodynamic Efficiency of Steady State Operations of MRUs

2017
Distillation columns and evaporation equipment are the main energy-consuming components utilized by offshore MRUs, besides several heating and cooling operations. One may ask about what would be the range of expected values of thermodynamic efficiencies for the main MRU operations.

Parametric analysis of steady-state operation of a CLHP

Applied Thermal Engineering, 2010
Cryogenic loop heat pipes (CLHPs) possess high pumping capability and good heat transfer performance that are important for effective and efficient cryogenic heat transport with considerable applications in space and terrestrial surroundings. Built on a previous model developed for a conventional loop heat pipe (Bai et al. [21]), this paper establishes
