More efficient magnetohydrodynamic energy conversion. Studies of dynamic electrode surfaces with high emissivity; Effektivare magnetohydrodynamisk energiomvandling; Studier av dynamiska elektrodytor med mycket laaga uttraedesarbeten

Abstract

The most important conclusion which can be drawn from our research on MHD generators is that the MHD technique will be competitive for the generation of electricity from combustion processes for a long time to come. A rapid introduction demands that MHD channels with higher plasma conductivity than the present ones will be developed. Such channels can be constructed also for the burning of biomass. They are however dependent on electrode surfaces which can emit and carry very large current densities. We have developed the only known method so far which can give such surfaces. They are covered by a layer of Rydberg matter, which is not stationary but is formed in the process. Current densities of the order of 100 000 A/m{sup 2} have been measured at low pressures with such dynamical electrode surfaces. A construction which should work also in high pressures in an MHD channel has been designed, but actual testing can not be performed since the support from NUTEK has been discontinued
