Title: Enhancement of heat removal using concave liquid metal targets for high-power accelerators.

Abstract

The need is increasing for development of high-power targets and beam dump areas for the production of intense beams of secondary particles. The severe constraints arising from a megawatt beam deposited on targets and absorbers call for nontrivial procedures to dilute the beam. This study describes the development of targets and absorbers and the advantages of using flowing liquid metal in concave channels first proposed by IFMIF to raise the liquid metal boiling point by increasing the pressure in liquid supported by a centrifugal force. Such flow with a back-wall is subject to Taylor-Couette instability. The instability can play a positive role of increasing the heat transfer from the hottest region in the target/absorber to the back-wall cooled by water. Results of theoretical analysis and numerical modeling of both targets and dump areas for the IFMIF, ILC, and RIA facilities are presented.

  • A numerical study was carried out to determine the effects of roughness on the thermal performance of Liquid Metal Reactor (LMR) decay heat removal systems for a range of possible design configurations and operating conditions. The ranges covered for relative rib height (e/D/sub h/), relative pitch (p/e) and flow attack angle were 0.026--0.103, 5--20 and 0--90 degrees, successively. The heat flux was varied between 1.1 and 21.5 kW/m/sup 2/ (0.1 and 2.0 kW/ft/sup 2/). Calculations were made for three cases: smooth duct with no ribs, ribs on both the guard vessel and collector wall, and ribs on the collector wallmore » only. The results indicate that significant benefits, amounting to nearly two-fold reductions in guard vessel and collector wall temperatures, can be realized by placing repeated ribs on both the guard vessel and the collector wall. The magnitudes of the reduction in the reactor vessel temperature are considerably smaller. In general, the level of improvement, be it with respect to temperature or heat flux, is only mildly affected by changes in rib height or pitch but exhibits greater sensitivity to the assumed value for the system form loss. When the ribs are placed only on the collector wall, the heat removal capability is substantially reduced.« less
  • A new design concept for a decay heat removal system in a liquid metal reactor is proposed. The new design utilizes a thermosyphon to enhance the heat removal capacity and its heat transfer characteristics are analyzed against the current PSDRS (Passive Safety Decay heat Removal System) in the KALIMER (Korea Advanced Liquid Metal Reactor) design. The preliminary analysis results show that the new design with a thermosyphon yields substantial increase of 20{approx}40% in the decay heat removal capacity compared to the current design that do not have the thermosyphon. The new design reduces the temperature rise in the cooling airmore » of the system and helps the surrounding structure in maintaining its mechanical integrity for long term operation at an accident. Also the analysis revealed the characteristics of the interactions among various heat transfer modes in the new design. (authors)« less
  • A conjugate heat transfer and thermal structural analysis was completed, with the objective of determining the following: Lead bismuth eutectic (LBE) peak temperature, free convective velocity patterns in the LBE, peak beam window temperature, and thermal stress/deformation in the window.
  • First experiments with turbulent duct flows of liquid metals exposed to magnetic fields have been performed in the mid-thirties of this century. Results of these experiments in which only the pressure drop along the duct was measured have been interpreted as strong suppression of turbulence leading ultimately to complete laminarization of the flow if the magnetic field becomes strong enough. Only 30 years later, in the mid-sixties, when local turbulence measurements were performed, it became clear that the phenomena under investigation are much more complicated and that not only full laminarization almost never occurs in magnetic fields. In fact intensitymore » of turbulence in many cases increases with the magnetic field. A strong anisotropy (with a tendency for two-dimensionality) of the modified turbulence was discovered and corresponding fundamental changes in the transfer of energy, heat and mass have been predicted. The present paper presents a brief historic review of the investigation of these phenomena and concentrates on results of studies done in the Center for MHD Studies of Ben Gurion University in Israel during the last decade. Main attention is given to the heat transfer enhancement phenomena. However for the analysis of experimental results and for the possibility to make some predictions and assessments beyond the domain of already performed experimental studies it is necessary to present and discuss also results related to velocities fluctuations, energy spectra, etc.« less
