Heat transfer performance of ceramic regenerator matrices with sine-duct shaped passages
Abstract
Experimental data relating to the heat transfer performance of sine-duct type passages in laminar flow ceramic regenerator matrices are reported. In particular, the range of aspect ratio (ratio of passage height to base) for which data is available is extended and the influence of passage geometry is considered in a detailed comparison of the measurements with previously reported data. The results indicate that no clear advantage is likely to be obtained with the higher aspect ratio matrices tested and overall the level of heat transfer is higher than may be expected from predictions with standard boundary conditions.
