On approximation properties of one discrete model of incompressible fluid
The approximation of fluid dynamics equations by a discrete model which is in fact symplified version of method of particles for incompressible fluid is studied. It is shown that when the discrete conditions of incompressibility are imposed only in the nodes of a certain grid, the momentum equation is approximated in the weak sense. The strong approximation takes place when the discrete conditions of incompressibility are satisfied for each particle.
