Analysis of the dynamic behavior of refrigerated spaces using air curtains
Jaramillo Ibarra, Julian Ernesto; Pérez Segarra, Carlos David; Oliva Llena, Asensio; Oliet Casasayas, Carles (2009-01-01)
Article
Accés restringit per política de l'editorialThis article is devoted to the study of air curtains applied to reduce the refrigerated chambers heat gains. The proposed strategy is based on the numerical simulation of air curtains by means of computational fluid dynamics ... -
Detailed numerical study of turbulent flows in air curtains
Jaramillo Ibarra, Julian Ernesto; Pérez Segarra, Carlos David; Lehmkuhl Barba, Oriol; Oliva Llena, Asensio (2010)
Comunicació de congrés
Accés restringit per política de l'editorialAir curtains are generally a set of vertical or horizontal plane jets used as ambient separator. In order to prevent entrainment, a good air curtain should provide a jet with low turbulence level, enough momentum to ... -
Numerical study of natural convection heat transfer from an isothermal thin plate.
Jaramillo Ibarra, Julian Ernesto; Oliva Llena, Asensio; Pérez Segarra, Carlos David; Soria Guerrero, Manel (2009)
Comunicació de congrés
Accés restringit per política de l'editorialIn this work detailed numerical simulations of natural convection heat transfer around an isothermal thin plate with different inclinations are carried out. The numerical approach is based on the finite volume technique ... -
Turbulence modelling and numerical issues: from RANS to DNS and LES
Pérez Segarra, Carlos David; Lehmkuhl Barba, Oriol; Jaramillo Ibarra, Julian Ernesto; Colomer Rey, Guillem; Oliva Llena, Asensio (2009)
Comunicació de congrés
Accés restringit per política de l'editorialThe objective of this work is to show possibilities and limitations of different turbulence models from RANS to DNS and LES. Firstly, standard approaches based on time averaging the governing equations (the so called ...
