| Abstract: | The effect of high-frequency translational vibrations on the occurrence of filtration convection in a plane horizontal layer
of a viscous incompressible liquid saturating a porous medium is studied. Constant temperature is maintained at the boundaries
of the layer. It is established that for any vibration direction different from the vertical (transverse) direction, convection
in gravity and thermal gravitational convection under both heating from above and heating from below can arise. In the case
of reduced gravity, values of the vibration parameter that lead to transition to zero gravity are established. The results
are obtained from an analysis of the averaged equations of filtration convection, derived for an arbitrary region.
