Gravitational field is modeled by the flow of the transient point dilatation, which is supposed to be continually emitted by a discontinuity of the turbulent fluid. Gravitational attraction arises from the contact interaction of the dilatation centers. Gravitational wave is viewed microscopically as the axisymmetric wave propagating at a high speed along a vortex tube.Other papers of the mechanalogy series can be found in /physics.gen-ph/9904General PhysicsFluid Dynamicstext
