Abstract: Basic equations are established for the two-dimensional hydraulic transient simulations in which the third dimension of the flow field varies spatially. A lattice Boltzmann scheme specially for solving these equations is developed by multi-scale analysis. After numerical verifications of the equations and scheme with typical flows, the two-dimensional hydraulic transients in a reinforced-concrete spiral case are simulated and analyzed. The reasonable results show that the lattice Boltzmann method has promising potential to simulate multi-dimensional hydraulic transients in practical engineering.
