Summary

An analytic equation of the mass flow rate through the bypass of double-inlet pulse tube refrigerators was obtained by an analysis of the pressure drop in the regenerator. The work loss through the bypass is discussed based on this eqution. The work loss ratio at 80 K with an ideal double-inlet is about 50, 30, 20 and 10% when the void volume ratio of the regenerator over the pulse tube is 0.5, 1.0, 2.0, and 4.0, respectively. The analytic results were compared with numerical results.
