摘要:In this paper, a new integral vorticity boundary condition has been developed and implemented to compute solution of nonprimitive Navier–Stokes equation. Global integral vorticity condition which is of primitive character can be considered to be of entirely different kind co...

摘要:Abstract(#br)Recently the biharmonic form of the Navier–Stokes (N–S) equations have been solved in various domains by using second order compact discretization. In this paper, we present a fourth order essentially compact (4OEC) finite difference scheme for the steady N...

摘要:Abstract(#br)A fourth order compact numerical scheme for variable coefficient parabolic problems with mixed derivatives is outlined. The finite difference scheme, presented here shows good wave resolution property and is stable. Implicit time discretization endows second order te...

摘要:Abstract(#br)In this paper, we develop a compact, implicit second order temporally and spatially accurate finite difference scheme for unsteady Navier–Stokes (N–S) equations for incompressible viscous flows. The scheme is specifically designed for flows in fluid-embedded bod...

摘要:Abstract(#br)In this paper, a new family of implicit compact finite difference schemes for computation of unsteady convection–diffusion equation with variable convection coefficient is proposed. The schemes which are fourth order accurate in space and second or lower order a...

摘要:Abstract(#br)The flow past a circular cylinder above some critical Reynolds number ( Re c ) is known to be asymmetric and, as a consequence, vortex shedding occurs naturally in physical situations. But in numerical simulations, especially in finite difference set up, it is w...

摘要:Summary(#br)The present work introduces an efficient technique for the deformation of block‐structured grids occurring in simulations of fluid–structure interaction (FSI) problems relying on large‐eddy simulation (LES). The proposed hybrid approach combines the advantag...

摘要:Abstract(#br)It has been shown that the Korteweg–de Vries equation, derived in inhomogeneous plasma, finds difficulty in obtaining the complete soliton solution and its propagation in plasma and thus fails to exhibit the actual nature of plasma acoustic-wave. The key here li...
