内容記述(抄録等)
This paper reports the numerical results on the effects of numerical parameters and the numerical methods of unsteady pressure in a discrete vortex method combined with a panel one. Calulations are carried out for a separated flow around a two-dimensional square cylinder. Results are as follows; Global flow characteristics are little affected by the shedding time interval of nascent vortex and the length of panel.
In unsteady pressure calculation, it is important to estimate the effect of rascent vortex.
