Grahic Jump Location
Illustration of two-dimensional Stokes flow past a stationary body located above an infinite plane wall
Grahic Jump Location
Streamline pattern of (a) antisymmetric and (b) symmetric flow around a corner with aperture angle 2α=3π/2. (c) Branches of the real and imaginary part of λ for antisymmetric flow (thick lines) and symmetric flow (thin lines); the solid lines represent the real part, and the dashed lines represent the imaginary part.
Grahic Jump Location
Force and torque exerted on a square cylinder with side length a whose center is located at distance a above the plane wall, plotted against the element stretch ratio β for Ns=8, 16, 32, and 64 boundary elements along each side. The highest curve in (a) and the lowest curve in (b) correspond to Ns=64.
Grahic Jump Location
Streamline pattern of shear flow past a square computed with the nearly optimal element distribution of 16 elements along each side, for inclination angle (a) 0, (b) π/4, and (c) π/2. (d) Flow past an inclined square whose center is located at a distance equal to five times the side length above the wall. The dots mark the location of the boundary element nodes.
