文摘

Channel-shaped heat exchanger improved indicated work of LTDSE. Channel-shape caused higher fluctuation of specific internal energy than conventional. LTDSE with channel-shaped heat exchangers and regenerators was tested. The new LTDSE obtained about 5 times the indicated power per displacer stroke volume. However, the polytropic index of the new LTDSE became larger than that of conventional.
