Abstract:

General wedge and corner problems lead to the introduction of complex Navier-Stokes equations of complex laminar motions the real parts of which describe real laminar flows. Under the nonslip condition at the surface of a dihedral angle, the general solution of the complex Navier-Stokes equations is established on the basis of the corresponding integral of the Stokes equations of slow motions. The latter integration is accomplished in terms of slow-motion eigenfunctions with real eigenvalues for infinite and semi-infinite plates and with complex eigenvalues for wedges and corners. The results obtained render valuable information about the flow properties at the leading or trailing edge of a dihedral angle. In particular, laminar flows around dihedral angles are shown to be nonanalytic in their dependence upon the corresponding wedge or corner angles. Author
