On the Dissipation of Primordial Turbulence in the Expanding Universe

Abstract
The decay laws of primordial turbulence and the heating rates by its dissipation are derived in the expanding medium, and it is shown that the matter in the expanding universe cannot be heated and kept at temperatures higher than 105 °K which are necessary for the galaxy formation by thermal instability. Moreover the effects of its dissipation on hydrodynamic instability are discussed.
