Ciclo de Curzon y Ahlborn para un gas de van der Waals

Abstract

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, $V_{max}\rightarrow V_{max}-b$ and $V_{min}\rightarrow V_{min}-b$, are obtained. The adiabatic branches in the cycle are consider non instantaneous.
