Economical flows are studied by means of a particle model. Simulation methods are applied to the problem and a theoretical framework is constructed. Adaptive methods for the analysis, the evaluation and the control of economical flows are deduced.

A comprehensive economic analysis of solid oxide fuel cell (SOFC) systems is presented in this paper. The analyzed system consists of a desulphurization system, a pre-reforming reactor, a fuel cell stack, an afterburner, heat exchangers, a power converter, a control system, blowers, pumps, start-up heaters and piping. Since most of these components are still in the prototype or early commercial...
