Computer design of permeable functionally graded materials for thermoelements in electric energy generation mode
Keywords:
computer design, permeable structuresAbstract
Based on the Pontryagin maximum principle of optimal control theory, a methodology for designing optimal functionally graded materials (FGM) for permeable thermoelectric elements is presented. An algorithm and a computer program have been created, which have been tested for finding the optimal FGM for n- and p-type legs based on Bi-Te-Se-Sb. It has been shown that under optimal conditions, 1.3-1.7 fold efficiency increase is achieved when using permeable generator thermoelements with FGM compared to traditional thermoelements with homogeneous legs.
