RT Journal Article ID 3cb5dce07f7d075e A1 Koneva, N. S. A1 Konev, S. V. T1 Special Features of Heat and Mass Exchange in Cryogenic Heat Accumulators JF Heat Transfer Research JO HTR YR 2003 FD 2004-04-04 VO 34 IS 7&8 OP 8 AB We analyze the operation of cryogenic heat accumulators with melting-crystallization phase changes. Numerical investigations are carried out for ethane (Tmel = 90 K), isopentane (Tmel =110 K), and heptane (Tmel = 190 K). We have designed the accumulators the charge and discharge of which is carried out with the aid of a heat pipe, i.e., thermal diode. Experimental investigations of the constructions developed made it possible to optimize the capillary structure with the accumulating medium. The advantages of conical capillaries are shown.
