Numerical Studies of the Influence of Geometrical Parameters of Heat Exchange Surfaces on the Efficiency of Heat Transfer Processes During the Flow Of Different Molecular Heat Carriers

The paper considers the influence of geometrical parameters of heat exchange surfaces of heat accumulators on the efficiency of heat transfer processes during the flow of different molecular heat carriers. A mockup sample of a single matrix module was taken as an object of research. The influence of geometrical parameters of heat accumulator matrix fins, such as height, width and number of fins, was investigated. Body and single matrix modules were made of niobium alloy. The flowing by a different molecular fluid at different temperatures was investigated.
