Popis: | The method of metal-hydride energy conversion predicted earlier as a result of numerical modeling and realized in the regime of heat waves that propagate in porous media is confirmed experimentally. The metal-hydride thermal converter is made up of two channels filled with a porous medium. The thermal converting properties of porous media are governed by metal-hydride elements (thermal-converter poles) distributed along the length of the channels. The elements of each channel contain zirconium-based alloys that are capable of rapidly and reversibly interacting with hydrogen with the formation of hydrides. The effect of the intensification of a cold wave (in a channel with low-temperature poles) is confirmed experimentally. Its amplitude attains the maximum low temperature that is permissible for a metal-hydride pair and exceeds the adiabatic temperature of the hydrogenation reaction in the channel of the thermal converter. |
