Wendelstein 7-X (W7-X) is a large optimized stellarator (B=2.5T, V=30m) aiming at demonstrating the reactor relevance of the optimized stellarators. In summer this year (2015) W7-X will begin its first operation phase (OP1.1) with five inertially cooled inboard limiters made of graphite. Assuming the heat loads can be spread out evenly between the limiters, 1 second discharges at 2 MW of heatin...
Several channel interference cancelation techniques have been proposed in different journals aiming at lowering to asymptotic bit error floors in optical OCDMA systems. These interference cancellation techniques are classified into two groups. One is based on the use of properties of sequence codes and another is based on the use of non linear elements in OCDMA systems. Optical hard-limiter is ...
To investigate the mechanisms leading to the heat deposition onto the first wall in the Scrape-Off Layer (SOL), we perform dedicated numerical non-linear simulations of the SOL plasma dynamics of a TCV discharge using the GBS code. The simulated parallel heat flux profiles on the limiter agree qualitatively with the experimental ones obtained by means of infrared thermography, showing a double ...
In this paper, we apply the local discontinuous Galerkin (LDG) method to 2D Keller– Segel (KS) chemotaxis model. We improve the results upon (Y. Epshteyn and A. Kurganov, SIAM Journal on Numerical Analysis, 47 (2008), 368-408) and give optimal rate of convergence under special finite element spaces. Moreover, to construct physically relevant numerical approximations, we develop a positivity-pre...
superconductor fault current limiter (sfcl) is an effective device to suppress high fault currents. this paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view. appropriate location and type of the limiters in a hv substation is selected by a qualitative approach based on the equal area criterion. study system is simulated by...
Presents corrections to the paper, (High Power X-band Monolithic GaAs PIN Balanced Limiter).
This paper provides an overview of a dynamic analysis carried out on a modified Nordic test system to determine the impact of the Powerformer on voltage stability. The unique aspects of the Powerformer will be highlighted and the modeling of long-term dynamic elements, especially those pertinent to the study of the Powerformer will be discussed. Overexcitation limiter models created for use in ...
In this paper we extend the recently developed third-order limiter function H 3L [J. Sci. Comput., (2016), 68(2), pp. 624–652] to make it applicable for more elaborate test cases in the context of finite volume schemes. This work covers the generalization to non-uniform grids in one and two space dimensions, as well as two-dimensional Cartesian grids with adaptive mesh refinement (AMR). The ext...
