Natural convection in a stack of horizontal plates in a differentially heated cavity
Résumé
Natural convection of gas in a differentially heated 2D
cavity partially filled with a stack of horizontal conducting
plates is investigated numerically. This specific situation
may be encountered in thermoacoustic wave generators.
The thin left and right fluid layers around the stack induce
convective movements which strongly affect the
temperature distribution. In order to predict the actual
temperature field for practical applications, the results are
analysed in terms of convection Darcy type flow through
a strongly anisotropic porous medium.
