1. Human thermal comfort: an irreversibility-based approach emulating empirical clothed-body correlations and the conceptual energy balance equation
Exergetic analysis can provide useful information as it enables the identification of irreversible phenomena bringing about entropy generation and, therefore, exergy losses (also referred to as irreversibilities). As far as human thermal comfort is concerned, irreversibilities can be evaluated based on parameters related to both the occupant and his surround

2. Análise energética e exergética da cadeia do gás natural líquido e a integração do processo de regaseificação com ciclos combinados de potência
Este trabalho estuda a cadeia do Gás Natural Líquido (GNL) e propõe utilizações para a recuperação da energia do processo de regaseificação em ciclos de potência acoplados. Primeiramente, aborda a cadeia de abastecimento do GNL, identificando e quantificando os pontos consumidores de energia, destruidores de exergia e a reevaporação de massa ocor

3. Hydrogen from biomass gas steam reforming for low temperature fuel cell: energy and exergy analysis
This work presents a method to analyze hydrogen production by biomass gasification, as well as electric power generation in small scale fuel cells. The proposed methodology is the thermodynamic modeling of a reaction system for the conversion of methane and carbon monoxide (steam reforming), as well as the energy balance of gaseous flow purification in PSA (

4. Analise termodinamica de um sistema de cogeração com gaseificação de licor negro / Termodynamic analysis of a cogeneration system with blak liquor gasification
The pulp and paper industries generate most part of energy for self consumption burning two different fuels: biomass and black liquor, which is more used than the first one. This industrial sector has been used cogeneration systems, to produce electric energy from the combustion of these fuels. In the last years an increase in the production of the industrie

5. Avaliação exergética dos efluentes do processo industrial do álcool / Exergetic assessment of effluents in the industrial alcohol process
In the production of ethyl alcohol as a fuel, the sugar and alcohol industry captures large volumes of water for steam generation, for cooling and as part of the process, generating large amounts of effluents. Using the energy produced by the burning of bagasse in the furnace for the transformation of water into steam, the industry generates its own electric

6. Modelagem, simulação e avaliação energetica e exergetica de secadores a leito deslizante
This work deals with the modelling and simulation of a moving bed dryer with the following flow configurations: counter-current; concurrent and mixed flow (counter + concurrent) with air recirculation. The mathematical modelling was based on the balance equations of mass and energy conservation, considering, for the partic1e moisture calculation, residence t
