Ja. Rochamartinez et al., A SIMPLE RELATIONSHIP BETWEEN THE SUNLIGHT CONCENTRATION FACTOR AND THE THERMAL CONDUCTANCE IN A CLASS OF PHOTOTHERMAL ENGINES, Journal of physics. D, Applied physics, 31(14), 1998, pp. 1742-1744
In this brief paper we present an addendum to a recently published ana
lysis of a photothermal engine model. Here, we numerically demonstrate
that the design parameters, the sunlight concentration factor and the
thermal conductances of materials employed as thermal conductors are
linked by a simple relationship, if one wishes to obtain the maximizat
ion of the power output of the photothermal engine.
