| Abstract | This paper presents an analytical solution for potential cross-flow in doubly-periodic in-line and staggered tube banks. The solution, in the form of a power series for the complex potential, is consistent with the well-known solution for a single cylinder. Results are tabulated for in-line square, rotated square, and equilateral triangle geometries for pitch-to-diameter ratio 1.25 less than or equal to s/d less than or equal to 2. Pressure contours and flow nets are presented for selected cases, together with local pressure coefficient and wall velocity data. |
