Design of Packed Bed Regenerator with By-pass

摘要

An explicit procedure for the design of a system containing a regenerator with bypass has been developed. Bypass of the regenerator during the energy retrieval process is controlled so that the temperature of the recombined fluid stream is held at a selected value. The procedure involves two sets of curves. The design curves relate the specific characteristics of the storage matrix and the mass rate of flow of the fluid through the regenerator. The performance curves relate the nondimensional length and period to the thermal ratio, maximum pressure drop, duration of hot period, and temperature of the combined fluid stream during the retrieval process. The mass of the storage material and dimensions of the regenerator are determined for the specified operating conditions.
