abstracts | The paper describes the SPH modeling of a plane problem of fluid flow around a rigid circular
cylinder. In the model considered, the cylinder is placed in a rectangular fluid domain at
a certain distance from a horizontal plane boundary, and it is subjected to fluid flow forces.
The fluid motion is induced by a piston type generator. The generator - fluid system starts to
move from rest at a certain moment of time. The work aims at a discrete description of the fluid
flow around the cylinder and, at the same time, calculation of the pressure distribution along
the circumference of the cylinder and the resultant of the pressure on the cylinder. In order to
solve the initial value problem considered, a new SPH formulation of boundary conditions on
the cylinder surface is proposed which match the physical condition for the fluid velocity at
this boundary. For a viscous fluid, an approximate description of the stress tensor is formulated
which allows to reduce the differentiation of field functions to the first order in calculating the
shear forces in the SPH approach. |
