Abstract: As feedwater heaters age, performance deteriorates and leaks invariably occur. In order to keep the heater functioning properly, and to avoid the possibility of water backing into the turbine ...

Abstract: The evolutionary process of system synthesis and the mathematical process of system optimization are integrated in one do-it-yourself software. A large number of flowsheet arrangements can be ...

Abstract: The following article completes the review of the development and state of engineering economic applications of the Second Law of Thermodynamics, which was begun in Part I (El-Sayed and Gaggioli, ...

Abstract: This paper presents the results of mathematical modeling of the performance of solid electrolyte fuel cells. The system of fundamental physical equations has been solved using a computer program ...

Abstract: The ideal voltage of steady-flow fuel cells is usually expressed by Emf = −ΔG°/nF where ΔG° is the “Gibbs free energy of reaction” for the oxidation of the fuel at the supposed ...

Abstract: The following report reviews the development and state of engineering economic applications of the second law of thermodynamics. It encompasses virtually all of the work carried out publicly in ...

Abstract: This paper presents a simple method for the optimal economic selection of pipe size and insulation thickness for steam piping systems. The primary operating costs inherent in any such system ...

Abstract: Energy conversion processes inherently have associated irreversibility. A better understanding of energy conversion will motivate intuition to create new energy-conversion and energy-utilization ...

Abstract: Dunbar, Lior and Gaggioli (1991) proposed a configuration of a fuel-cell-topped electrical Rankine power generating station and analyzed its performance. That study revealed that the fuel-cell ...
