Modeling a no-slip flow boundary with an external force field
A novel technique related to Peskin's immersed boundary approach [\textit{C. S. Peskin}, J. Comput. Phys. 25, 220-252 (1977; Zbl 0403.76100)] is used to introduce solid surfaces into a simulated flow field. Examples are presented which include 2D flow around cylinders, 3D turbulent channel flow where one boundary is simulated with a force field, and turbulent channel flow over a riblet-covered surface. All simulations are done with a spectral code in a single computational domain without any mapping of the mesh.
