Spatial decay for a model of double diffusive convection in Darcy and Brinkman flows

  • L. E. Payne
  • J. C. Song


A fluid which contains a solute is assumed to flow through a semi-infinite pipe. We study the problem of double diffusive convection for steady state Brinkman and Darcy flows using a model of Straughan and Hutter [14]. Under appropriate hypotheses we establish the exponential decay of solutions.

Key words. Double Diffusion, Darcy and Brinkman flow, decay estimates, a priori bounds.
