Abstract

Fluid forces arising from transversely oscillating circular cylinders in fluid at rest are studied by numerical solution of the two-dimensional unsteady incompressible Navier-Stokes equations defined by a primitive-variable formulation. A validated cell viscous boundary element scheme developed by the authors[l] is used in the numerical computations. In this scheme, a hybrid approach is adopted utilis- ing boundary element and finite element methods. Cell equations are generated using the principles of boundary element theory and the global equations are de- rived followi
