Thermodynamic design of a power optimized irreversible thermionic generator

IECEC-97 Proceedings of the Thirty-Second Intersociety Energy Conversion Engineering Conference (Cat. No.97CH6203), 1997
The operating temperatures of the electrodes in a thermionic (TI) energy generator can better be determined through thermodynamic optimization rather than through heuristic principles. Since the power output of a TI generator has high functional dependence on operating temperatures, choice of these temperatures becomes a crucial aspect in the design of

Thermodynamic analysis and optimization of a flash-binary geothermal power generation system

Geothermics, 2015
Abstract Due to a good behavior of ammonia–water mixture during the two-phase heat addition process, a Kalina cycle using ammonia–water as working fluid is employed to further recover the heat of geothermal water from a flash cycle for geothermal resources.

Thermodynamic performance optimization of the absorption-generation process in an absorption refrigeration cycle

Energy Conversion and Management, 2016
Abstract The absorption refrigeration cycle is a basic cycle that establishes the systems for utilizing mid-low temperature heat sources. A new thermal compressor model with a key parameter of boost pressure ratio is proposed to optimize the absorption-generation process. The ultimate generation pressure and boost pressure ratio are used to represent

Geometric and Thermodynamic Optimization of a Heat Recovery Steam Generator: A Constructal Design

Journal of Heat Transfer, 2012
Heat recovery steam generator (HRSG) is a critically important subsystem of a combined cycle. The global objective of a HRSG is to heat the stream of water. The HRSG is composed of three major sections, including an economizer, an evaporator, and a superheater. In this study, a water tube HRSG is considered and its main design features are deduced from

Thermodynamic optimization of biomass gasification for decentralized power generation and Fischer–Tropsch synthesis

Energy, 2010
Abstract In recent years, biomass gasification has emerged as a viable option for decentralized power generation, especially in developing countries. Another potential use of producer gas from biomass gasification is in terms of feedstock for Fischer–Tropsch (FT) synthesis – a process for manufacture of synthetic gasoline and diesel.

Geometric optimization of two-stage thermoelectric generator using genetic algorithms and thermodynamic analysis

Energy, 2019
Abstract Multi-objective genetic algorithms are used to optimize the structure, assignment of configuration and load resistance of a two-stage thermoelectric generator, where Skutterudite and Bi2Te3 are chosen as upper stage and lower stage TE leg materials, respectively. Heat convection and radiation are considered on the top of the upper substrate.

Optimal thermodynamic and economic volume of a heat recovery steam generator by constructal design

International Communications in Heat and Mass Transfer, 2012
Abstract The ratios of gas flow to steam flow are huge in heat recovery steam generators (HRSGs) compared to other steam generators. So the volume which is occupied by components of the HRSG such as economizer, evaporator and superheater is important factor when the HRSG is applied in structures including buildings and ships.
