The high-speed GSMAC-FEM (generalized simplified marker and cell finite-element method) is a stable and cost-efficient FEM method for incompressible viscous flow analysis. Using the high-speed GSMAC-FEM, the gas flow and the heat transfer in the moving-bed heat exchanger are analyzed. In the Navier-Stokes equation, Ergun's equation is used for body force which is a drag caused by the small-scale flow around pebbles, and the experimental heat transfer coefficient is used for the computation of heat sink and heat source terms in gas and pebble energy equations, respectively. The analyzed pressure distributions and temperature distributions nearly agree with the experimental results. Using this scheme, a high-efficiency heat exchanger, i.e. heat exchanger with uniform gas flow, can be designed cost-effectively.
