    Air 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)

    In 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 ...
