where S*" is the entropy generated per unit area of the RI I converter. Similar balance equations may be written for the IIW converter: In (1-4) Ts and Tc are the ambient and converter temperatures while 4> and ip refer to energy and entropy fluxes respectively. The subscript pc denotes a flux from the pump to RI I and the subscript cs denotes a flux from RI I to the sink. The return flux from RI I to the pump is also considered (cp). RI I supplies the heat flux Q' to IIW. This heat flux is accompanied by the entropy flux which is the rate of entropy generation while the work produced and the heat transferred from IIW to the sink are W and Q. We may determine the power generated by manipulating equations 1-4: Considering isentropic black body radiation the total energy and entropy fluxes emitted by component i towards component j (i,j = p,c,s) are given by: [13]
