This paper proposes a methodology aiming at determining the most influent working variables and geometrical parameters over the pressure drop and heat transfer during the condensation process of several refrigerant gases using heat exchangers with pipes mini channels technology. A multi-criteria decision making (MCDM) methodology was used; this MCDM includes a mathematical method call... https://thebookmarkid.com/story19599519/integrando-a-hist%C3%B3ria-oral-e-as-narrativas-a-abordagens-pedag%C3%B3gicas-problematizadoras-na-forma%C3%A7%C3%A3o-inicial-de-professores-de-matem%C3%A1tica
