Magnetohydrodynamic flow in the European SCLL blanket concept
The pressure drop and flow patterns of fully developed liquid metal flow in a typical geometry of the European SCLL blanket exposed to a uniform magnetic field has been evaluated. The calculations for an outboard blanket in a field of B_0 = 4 T show that the pressure gradient in ducts made by electrically insulating walls is about #nabla#p = 0.0567...
JET steady state ITB operation with active control of the pressure profile

JET steady state ITB operation with active control of the pressure profile
Stationary operations have been achieved at JET in ITBs scenarios, with the discharge time limited only by plant constraints. Full current drive was obtained, all over the high performance phase, with the current density profile frozen by using Lower Hybrid current drive. For the first time a feed-back control on the total pressure and on the elect...

Investigations for the transient behaviour of the accumulator's discharge flow in pressurized water reactors in consider...
Within the scope of German reactor safety research the thermal-hydraulic behaviour in accumulators was investigated experimentally and analytically for transient injection. The paper includes the description of two test facilities used for separate effect experiments for the discharge flow of accumulators. Results derived from experiments at a glas...

Modelling of diamagnetic stabilization of ideal MHD eigenmodes associated with the transport barrier
A new code, MISHKA-D (Drift MHD), has been developed as an extension of the ideal MHD code MISHKA-1 in order to investigate the finite gyroradius stabilizing effect of ion diamagnetic drift frequency, #omega#_*_i, on linear ideal MHD eigenmodes in tokamaks with shaped plasma cross-section. The MISHKA-D code gives a self-consistent computation of bo...
Idle load losses of an injection-lubricated spur gear drive / Untersuchungen zu den Leerlaufverlusten eines einspritzges...
Turbogetriebe werden vorzugsweise zur Drehzahlwandlung zwischen Turbinen und Generatoren oder Verdichtern eingesetzt. Die groessten bekannten Ausfuehrungen solcher Getriebe liegen derzeit bei Leistungen bis P_A=100 MW mit Antriebsdrehzahlen bis n_T=7200 min"-"1. Mit der stetigen Weiterentwicklung der Antriebsmaschinen wachsen auch die Anforderungen...
