Energy conversion theorems for some linear steadystates
Abstract
One of the main issues that real energy converters present, when they produce effective work, is the inevitable entropy production. Within the context of Nonequilibrium Thermodynamics, entropy production tends to energetically degrade manmade or living systems. On the other hand, it is also not useful to think about designing an energy converter that works in the socalled minimum entropy production regime since the effective power output and efficiency are zero. In this manuscript, we establish some Energy Conversion Theorems analogous to Prigogine's one, their purpose is to reveal tradeoffs between design and the socalled operation modes for (2 x 2)linear isothermal energy converters. The objective functions that give rise to those thermodynamic constraints show stability. A twomeshes electric circuit was built as an example to demonstrate the Theorems' validity. Likewise, we reveal a type of energetic hierarchy for power output, efficiency and dissipation function when the circuit is tuned to any of the operating regimes studied here: maximum power output ($MPO$), maximum efficient power ($MP_{\eta}$), maximum omega function ($M{\Omega}$), maximum ecological function ($MEF$), maximum efficiency ($M{\eta}$) and minimum dissipation function ($mdf$).
