The features of air suspension flow past a cube are investigated. A solution is found to the
plane problem of the flow of two-phase medium (water drops with a volume fraction of no more
than 1
past a body with square cross-section. The fields of distribution of physical quantities (pressure,
velocity, concentration) at fixed time instants and the dynamics of their variation are presented
and analyzed. The local features of the air suspension flow in the near wake are compared with
the topology of the one-phase air flow. It is shown that the presence of the second phase in
the air suspension leads to turbulization of the flow at small Reynolds numbers and causes the
formation of a viscous vortex street in the modes of laminar flow in the subsonic region. An
estimate is given of the sufficiency of the distance of the boundaries of the computational region
from the cube for the solution of the plane problem of external multiphase aerodynamics.
