Applying second law of thermodynamic for optimization of horizontal steam generator
Progress in Nuclear Energy, 2021Abstract One of the essential components in a pressurized water reactor is the steam generator (SG) that has an important role in efficiency of nuclear power plants. In the present work, a horizontal steam generator (HSG) was investigated based on entropy generation as a consequence of second law of thermodynamic.

Thermodynamic optimizing of pressure-retarded osmosis power generation systems
Journal of Membrane Science, 1999A transport equation for a solution flow increasing due to osmosis inside a hollow cylindrical fibre is derived. The equation can be applied for either direct, pressure-retarded or reverse osmosis, when the membrane is highly selective. This transport equation is used to study theoretically the net power delivered, and the entropy generated by two ...

Thermodynamic performance optimization for an irreversible vacuum thermionic generator
The European Physical Journal Plus, 2017Theoretical model of an irreversible vacuum thermionic generator considering external and internal finite rate heat transfer is established in this paper. By assuming radiative heat transfer processes, the general expressions of performance parameters are derived based on non-equilibrium thermodynamics and finite-time thermodynamics (FTT).

Thermodynamic optimization method of regenerator of gas turbine with entropy generation
Journal of Heat Recovery Systems, 1986Abstract In the design of the heat exchangers, the enhancement of heat transfer suraace area is effective to reduce the loss due to the fluid-to-fluid temperature difference. It, however, leads to the increase of the pressure loss in the channel. The optimum working condition must be determined by taking these trade of conditions into account.

Applicability of the minimum entropy generation method for optimizing thermodynamic cycles
Chinese Physics B, 2013Entropy generation is often used as a figure of merit in thermodynamic cycle optimizations. In this paper, it is shown that the applicability of the minimum entropy generation method to optimizing output power is conditional. The minimum entropy generation rate and the minimum entropy generation number do not correspond to the maximum output power when
