| Popis: | The results of a computational and experimental investigation of nuclear-induced electrical conductivity enhancement in 3He is discussed with application to magnetohydrodynamic (MHD) energy conversion. Calculations based on the standard model of interactions and conductivity in a gas of partially ionized 3He suggest a region of conditions not previously considered may provide significant conductivity enhancement. Specifically, at densities less than standard atmospheric density and neutron flux greater than 1×1012/cm2 s, conductivity greater than 10 mho/m may be achievable. These calculations also suggest conductivities of several hundred mho/m may be possible for an achievable range of conditions. Additionally, the calculations show that nuclear-induced conductivity is strongly density dependent and weakly temperature dependent. Therefore, higher flow velocities, and hence higher power densities than those typical in traditional MHD channels utilizing thermal ionization would be possible. Experiments wer... |
