Nearly Singular Integrals in 3D Stokes Flow
Nearly Singular Integrals in 3D Stokes Flow
Abstract A straightforward method is presented for computing three-dimensional Stokes flow, due to forces on a surface, with high accuracy at points near the surface. The flow quantities are written as boundary integrals using the free-space Green’s function. To evaluate the integrals near the boundary, the singular kernels are regularized …
