High heat flux target for intense neutron source

Review of Scientific Instruments, 1984
A 200-kV, 200-mA deuterium ion accelerator has been developed to simulate the operation of an intense neutron source for use in cancer therapy. The thin-film ScD2 target for the neutron source is supported on a water-cooled copper substrate designed to dissipate 40 MW/m2 at a surface temperature of 450 °C.

Thermal Optimization of Circular Bodies Submitted to an Intense Heat Flux by Constructal Design

2009 3rd Southern Conference on Computational Modeling, 2009
The present work studies the optimization of a circular body with an intense heat flux by Constructal Design. The problem concerns the minimization of the global thermal resistance of a three-dimensional structure submitted to an intense uniform heat flux, which is cooled through microchannels inserted in the circular body.

Assessment of Explicit Algebraic Stress/Heat-Flux Models for Reduction of Heat Transfer in a Vertical Pipe with Intense Heating

open access: yesTransactions of the Korean Society of Mechanical Engineers B, 2003
This paper assesses the prediction performance of explicit algebraic stress and heat-flux models for reduction of heat transfer coefficient in a strongly-heated vertical tube. Two explicit algebraic stress models and four explicit algebraic heat-flux models are selected for assessment.

The Importance of Photospheric Intense Flux Tubes for Coronal Heating

open access: yesSolar Physics, 1997
Dissipation of magnetic energy in the corona requires the creation of very fine scale-lengths because of the high magnetic Reynolds number of the plasma. The formation of current sheets is a natural possible solution to this problem and it is now known that a magnetic field that is stressed by continous photospheric motions through a series of ...

The time-dependence of intense archeomagnetic flux patches

open access: yesJournal of Geophysical Research, 2011
International audience[1] The long‐term temporal behavior of intense geomagnetic flux patches at the core‐mantle boundary and the relation with lower mantle lateral heterogeneity are under debate.
