Using an interpolation-based strategy, the lattice Boltzmann method is extended to general curvilinear coordinate systems. As an example, a cylindrical coordinate system is used to simulate two-dimensional flow around a circular cylinder. Numerical simulations are carried out for impulsive initial conditions with Reynolds numbers up to \(10^4\). The agreement of our results with previous computational and experimental results is satisfactory.
