Abstract:
The stability problem is considered for a lattice Boltzmann kinetic scheme
for simulating the plane flows of a viscous fluid. Stability is studied for
two steady modes of flow in an unbounded domain. The stability analysis is
performed with respect to initial data using the Neumann method in a linear
approximation. A number of stability domains are constructed and studied in
the input parameter space. It is shown that the scheme under consideration
is conditionally stable.
