Résumé

The dynamic behaviour of the temperature profiles in the regenerator and in the gas near the hot and cold ends of the tube are discussed. The operation of a single-orifice pulse tube is described in general thermodynamic terms. This approach is extended to the double-inlet pulse tube. Expressions for the various sources of entropy are derived and lead to the establishing of a relation for the COP. This study shows how the second inlet improves the operation of the pulse tube and what the optimal settings are.
