(a) The distribution of the scaled pressure rp′/r0 on the r-axis at t = 5.12 µs. The analytical (−) and numerical (◦) solutions are compared. The numerical solution with and without the geometric component in the source term, G(t)), (×) are plotted. One of every five data points are shown for the numerical solutions. (b) The magnitude of the scaled error between the same analytical and numerical solutions, E=r((pNumelpAnal)/pAnal)/r0, on the r-axis at t = 5.12 µs. The error in terms of the numerical solution with the geometric component (◦) and without the geometric component (×) in the source term are plotted. (c)L1,2,∞-norm of the error between the analytical solution and the numerical solution at t = 5.12 µs as a function of the grid size (2N × N). Reference slopes for the first and second order convergence are included.
