Figure 5From: A mass-conservative higher-order ADI method for solving unsteady convection–diffusion equationsContour lines of pulses in the sub-region \(1.2\le x\), \(y \le 1.8\) at final time \(t=0.01\) with \(\mathit{Pe}=100\) and \(\tau =2.5\times 10^{-5}\): (a) exact and present DHOD-ADI, (b) exact and HOC-ADI, (c) exact and EHOC-ADI, and (d) exact and RHOC-ADI. Dash-dot contour lines in (a)–(d) correspond to numerical solutionsBack to article page
