Numerical investigation of energy desorption from magnesium nickel hydride based thermal energy storage system

The use of dual metal hydride system for thermal energy storage consists high and low-temperature hydrides. In this study, a 3D cylindrical Magnesium Nickel bed is analyzed discharge. discharge from initially at temperature 400 K, heat transfer fluid 500 K supplied to extract the generated due exothermic chemical reaction. article, variation number tubes effect aspect ratio (ratio diameter height) on desorption performed. optimal determined various ratios. with an increase in analyzed. study characteristics three ratios 0.5, 1, 2. desorbed, net are adequate AR 2 identified as 32, 48, 72, respectively. cumulative released MH 350.94 kJ, 330.56 310.42 will be useful designing optimized reactor applications.
