1D and 2D Numerical Modeling for Solving Dam-Break Flow Problems Using Finite Volume Method

Figure 5

Comparisons of experiments and numerical simulations—(a) and (b) when 𝑡=0.56 sec, dam-break flow arrives to the columns; (c) and (d) when 𝑡=0.625 sec, dam-break flow moves to the middle of the columns; (e) and (f) when 𝑡=0.725 sec, dam-break flow surrounds the columns and forms vortexes; (g) and (h) when 𝑡=0.925 sec, dam-break flow touches the boundary of tank; (i) and (j) when 𝑡=1.75 sec, the flow returns to the location of gate.
