Abstract:The non-Oberbeck–Boussinesq effects on the stability of a vertical natural convection boundary layer are investigated using the linearised disturbance equations for air flows up to a temperature difference of
$\Delta T=100\,{\rm K}$
. Based on the linear stability results, the neutral curve is shown to be sensitive to the choice of reference temperature. When evaluated using the film temperature
$T_f$
, a lower film Grashof number is required to trigger the… Show more
