Summary: In situ adaptive tabulation has been used to store equilibria states in a tree-like structure to be used in prediction of local condensation rates in CFD simulations of heat exchanger tubes. An interface to several tools to compute chemical equilibrium in flue gas compositions was developed. The results show a reduction of computation times at least by a factor of 8 (Table 4). Relative tolerances of 10 - 4 are sufficient to interpolate the table. Simulations indicate that mesh resolution is more important than a smaller tolerance.
