LADINO-LUNA, D.. Ciclo de Curzon y Ahlborn para un gas de van der Waals. Rev. mex. fis. [online]. 2002, vol.48, n.6, pp.575-578. ISSN 0035-001X.

For a Curzon and Ahlborn type heat engine with a van der Waals gas like a working substance, using maximization of power and maximization of ecological function, it is shown that the same expression of the efficiency for the ideal gas case as working substance, with the substitution of maximum volume and minimum volume spanned by the engine, V_max → V_max - b and V_min → V_min - b, are obtained. The adiabatic branches in the cycle are consider non instantaneous.

Palavras-chave : Finite time thermodynamics; van der Waals gas.
