Studies on a High-Temperature Regenerative Heat Exchanger for Closed-Cycle MHD Power Generation

Studies on a High-Temperature Regenerative Heat Exchanger for Closed-Cycle MHD Power Generation

A numerical heat-transfer analysis in the combustion chamber of a pebble bed regenerative heat exchanger has been carried out for the heating period. A radiative zone method coupled with chemical and two-dimensional fluid dynamic calculations is employed in the analysis, and the results agree well with the measured data. The analysis also shows that higher temperature can be obtained at the top of the pebble bed by optimizing the geometries of the combustion chamber and the burner.
