On the one hand their functioning is better understood and on the other the development of new materials and technologies leads to greater efficiences. A theoretical model is reported on in which irreversibility is partially taken into accounts as well as on the efficient combination of gas and vapour turbinesOb naraščajoči porabi energije imajo toplotni stroji v elektrarnah še naprej odločilno vlogo. Na eni strani bolje razumemo njihovo delovanje, na drugi razvoj novih snovi in tehnik omogoča večje izkoridtke. Prispevek na kratko poroča o računu, ki delno upošteva ireverzibilnost, in o učinkoviti povezavi plinskih in parnih turbinTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo matematikov, fizikov in astronomov
