Dependence of flow features in two-dimensional (2D) vortex simulation on time-in-tegration scheme is studied. Three types of scheme are applied to a flow past an im-pulsively started flat plate set normal to the freestream; the first-order Euler scheme,the second-order Adams-Bashforth scheme and the fourth-order Runge-Kuttascheme. Calculated results are compared with experiments. The Adams-Bashforthscheme and the Runge-Kutta scheme prove to give flow features close to each other,while the Euler scheme gives somewhat different results from the others. As to the tem-poral growth of separation bubbles, the Cuter scheme gives tlae best agreement withexperiments. Effects of parameters such as the numerical core-radius and the time-step are also studied.2D vortex simulation, effect of schemes, effect of parameters
