This paper has developed a formulation of fluid motion and entropy production in microchannels. We have developed the formulations for pressure driven flow, flow under electric forces and flow under ferromagnetic forces. Friction, thermal and electromagnetic irreversibilities have significance in energy efficiency of microfluid systems. The results indicate that entropy and the Second Law have practical significance in electrokinetic liquid transport through microchannels.

W artykule pokazano rozwój sformułowania ruchu płynu i entropii produkowanej w mikrokanalikach. Rozwinięte zostały sformułowania dla przepływów poddanych ciśnieniu, przepływów w polu elektrycznym i przepływów poddanych siłom ferromagnetycznym. Ciśnienie, cieplna i elektromagnetyczna nieodwracalność mają istotne znaczenie dla efektywności energetycznej systemów mikroprzepływowych. Wyniki wskazują, że entropia i drugie prawo termodynamiki mają praktyczbe znaczenie w transporcie płynów elektrokinetycznych przez mikrokanaliki.
