    Abstract

    A mathematical model for the brine migration in rock salt around an infinite line heat source is set up. The temperature field around the time dependent heat source is calculated by use of Green functions. Numerical solutions are obtained by the computer program PSAMA and results are compared with hand calculations for certain simple cases.

    By general considerations of the migration field approximate values of the brine inflow, which are independent of the source shape, is obtained and these results are used to estimate the agreement with the experimental results from Project Salt Vault.
