Pressure Distribution around a Circular Cylinder by Source Panel Method

Let us consider a circular cylinder with a distribution of source panels on its circumference, as shown in Figure 7.7.

To evaluate the integral Ij, let us consider the ith and jth panels, as illustrated in Figure 7.8.

The control point on the ith panel is (x;, y;). Coordinates of boundary points of ith panel are (x;, y;) and (x;+1, y;+i). An elemental length segment dsj on the jth panel is at a distance of r;j from (x;, y;), as shown in Figure 7.8. The point (xj, yj) is the running point on the jth panel. The boundary points of the
