Material Optimization and Parameter Estimation of Generator Modules for Heat Recuperators
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 1
Abstract
Use of thermoelectric power converters in heat recuperators is considered as an efficient, cheap and environmentally safe method for recovery of thermal waste from industrial installations and internal combustion engines. Results are presented of composition optimization for materials based on BiTe, PbTe, TAGS (AgSbTe-GeTe), ZnSb, Mg and Mn silicides, CoSb scutterudites that are reasonable to be used for generator modules in recuperators with the operating temperature range 30 to 500 °C. Estimates are made and comparative analysis is performed of maximum efficiency of modules of these materials with the legs of homogeneous, functionally-graded, segmented and stage structures. Optimization and efficiency calculation are performed by computer methods based on optimal control theory. The results of calculations are confirmed by an example of experimental research on characteristics of two-stage modules made of materials based on BiTe, PbTe and TAGS.
