PROPAGATION OF WAVES OF METAL-HYDRIDE THERMAL
CONVERSION IN BLOWN-THROUGH POROUS MEDIA

A method of metal-hydride thermal conversion that is an alternative
to the traditional method is proposed and investigated. The unlike
poles of metal-hydride thermal converters are distributed in pairs
inside parallel channels. The channels are blown through with
a heat-transfer agent. Thermal conversion develops as a set of
successive heat waves. By a numerical-modeling method it is shown
that the maximum thermal effect is attained in synchronous motion
of the heat wave and the heat source (or sink) that accompanies the
phase transition in the succession of metal-hydride poles. The
results are presented in a form convenient for prediction of the
thermal and energy efficiency of the proposed thermal-conversion
method in real devices.
