VILLANUEVA-MARROQUIN, J.  e  BARRAGAN, D.. Analysis of entropy production in a thermal engine powered by a nonlinear chemical system. Rev. Mex. Ing. Quím [online]. 2009, vol.8, n.1, pp.145-152. ISSN 1665-2738.

Second law optimization is applied to study a thermal engine driven by a thermokinetic oscillator. The Sal'nikov model is used to modeling the net process AB, which for given values of the control parameters exhibits nonlinear behavior like oscillations in temperature and concentrations. Constant of global heat transfer in W m^-2 K^-1for the engine which minimizes the rate of entropy production during transformation is obtained after numerical evaluation.

Palavras-chave : second law optimization; rate of entropy production; thermodynamic dissipation; Sal'nikov model; thermokinetic oscillator..
