dc.description.abstractThe Honigmann process is a thermochemical energy storage converting low temperature heat into mechanical work. To control and optimize the operation of the storage, the Honigmann process is simulated numerically using a set of differential-algebraic equations (DAEs) as governing equations. We analyze this DAE regarding its solvability, the uniqueness of solutions and the efficiency of numerical solvers. We identify the steps of the process modeled by a reliable, uniquely solvable mathematical model and point out those steps, where the mathematical model may lead to ambiguous solutions. For the steps of the process described by a uniquely solvable model, we compare several numerical solvers with respect to efficiency and accuracy.en
